I’ve used Microsoft OneNote daily for three years across Windows, マック and mobile devices.
Every step below comes from real note-taking sessions, not vendor screenshots.
Microsoft OneNote is a free-form digital notebook built for people who hate rigid documents.
Most users only ever type on one page and stop there.
This onenote tutorial shows you how to use Microsoft OneNote feature by feature.
Follow it once and you will master Microsoft OneNote faster than any manual allows.
Each section below covers one feature, with the exact clicks I use every week.
Microsoft OneNote チュートリアル
This How to Use Microsoft OneNote tutorial walks through setup, daily note taking and the advanced features most people never open.
Microsoft OneNote の利用開始
Before any feature makes sense, finish this one-time setup.
It takes about three minutes on a computer or phone.
まずはこちらの簡単な概要をご覧ください。
それでは、各ステップを順を追って見ていきましょう。
ステップ1：アカウントを作成する
Go to the Microsoft OneNote website and click Sign Up.
Sign in instead if you already own a Microsoft account from Office or Xbox.
✓ チェックポイント: チェックしてください 受信トレイ 確認メールについて。
Step 2: Open the App on Your Devices
OneNote comes pre-installed on most Windows PCs as a desktop app.
Mac, iOS, Android and Chrome users download it from their store, or work online in a browser.
The tabs across the top — Home, Insert, Draw and View — hold every tool in the app.
Here is what my own setup looks like after three years of use:
✓ チェックポイント: You should see the notebook list on the left.
ステップ3：最初のノートを作成する
Click Add Notebook and name your new notebook something plain like Work or School.
Add a new section for each topic, then add a page inside that section.
OneNote saves and syncs your データ automatically, so there is no Save button to hunt for.
You can also delete or rename any page by right-clicking its title in the page list.
Drag section tabs left or right to reorder them once your notebook grows.
✅ 完了: You’re ready to use every feature below.
Microsoft OneNote Copilot の使い方
副操縦士 lets you draft, summarize and rewrite notes without leaving the page.
It sits inside the app, so you never paste notes into a separate AIツール.
I use it most on messy call notes that need to become a short brief.
以下に、その使用方法をステップごとに説明します。
Step 1: Open the Page You Want to Work On
Open any page in your current notebook and place the cursor in the body.
Copilot reads whatever sits on that page, including pasted documents.
Step 2: Launch Copilot From the Home Tab
Click the Copilot icon on the Home tab and type a plain request.
Ask it to pull key information out of a long meeting page.
これがその様子です。
✓ チェックポイント: The change appears on the page straight away.
Step 3: Edit the Draft Into Your Own Words
Insert the draft, then edit any wording that does not sound like you.
Turn loose ideas into a short list of tasks before you close the page.
Copilot works best on pages that already hold real detail, not empty outlines.
✅ 結果: A messy wall of 文章 becomes a tidy summary and a clear task list.
💡 プロのヒント: Ask Copilot to rewrite a rough paragraph as three bullet points. It is faster than reformatting by hand.
How to Use Microsoft OneNote Sketch & Annotate Tool
スケッチと注釈 lets you write, draw and mark up notes with a pen or your finger.
This is the feature that makes OneNote feel like paper rather than a text box.
Whiteboard photos, marked-up screenshots and rough wireframes all live here.
以下に、その使用方法をステップごとに説明します。
ステップ1：描画タブを開きます
Open the Draw tab and pick a pen thickness and colour.
A stylus works best, but a mouse or finger is fine for quick drawing.
Step 2: Write or Sketch Diagrams on the Page
Write directly on the page, or sketch diagrams beside your typed notes.
Use the Insert tab to drop in pictures and annotate them on top.
これがその様子です。
✓ チェックポイント: The change appears on the page straight away.
Step 3: Highlight and Convert Your Ink
Highlight the lines that matter with the highlighter pen.
Select your handwritten notes and choose Ink to Text to convert them.
Ink stays editable, so you can move a drawing around the page later.
✅ 結果: Your sketches and handwriting sit on the same page as your typed notes.
💡 プロのヒント: OneNote indexes ink, so search finds words inside handwritten notes and pictures. Most people never test this.
How to Use Microsoft OneNote Collaborator
コラボレーション lets you let a whole team read and edit the same page at the same time.
Edits appear with the author name beside them, so nothing gets overwritten silently.
Project notebooks, meeting agendas and shared research all work well this way.
以下に、その使用方法をステップごとに説明します。
Step 1: Store the Notebook in OneDrive
Shared notebooks must live in OneDrive, not on your local computer.
Move the notebook first, or sharing options stay greyed out.
Step 2: Share the Link With Your Team
Click Share, then send an email invite or copy a link.
Set permissions per person, and add an expiry date for outside guests.
これがその様子です。
✓ チェックポイント: The change appears on the page straight away.
Step 3: Work Together in Microsoft Teams
Pin the notebook as a tab inside a Microsoft Teams channel.
Post an update on the shared page and everyone sees the edit live.
Version history lets you roll a page back if someone deletes the wrong block.
✅ 結果: Your team keeps meeting notes and files in one place instead of five inboxes.
💡 プロのヒント: Share a single page as a read-only snapshot when a client only needs one section, not the whole notebook.
How to Use Microsoft OneNote Voice Transcriber
声 転写 lets you capture audio and turn spoken words into searchable text.
Recording and typing at once means you stop trying to write down every word.
Interviews, lectures and client calls are the obvious candidates.
以下に、その使用方法をステップごとに説明します。
Step 1: Start a Recording From the Insert Tab
Open the Insert tab and click Audio to start recording.
The same tab handles online videos and other multimedia content.
Step 2: Type While the Audio Runs
Keep typing during the meeting as the recording continues.
OneNote timestamps each paragraph against the matching moment in the audio.
これがその様子です。
✓ チェックポイント: The change appears on the page straight away.
Step 3: Transcribe and Review
Use Dictate on the Home tab to convert speech into text directly.
Play back the audio files later and jump straight to any timestamped line.
Always tell people in the room that you are recording before you press start.
✅ 結果: You leave a meeting with a recording and a written record you can search.
💡 プロのヒント: Say the speaker name out loud before each point. Your transcript then reads like a labelled interview.
How to Use Microsoft OneNote Educator
ノート教育 lets you organize lesson plans, class notes and study material for school.
Class Notebook adds a 教師 view on top of the normal notebook structure.
It also suits any trainer running the same course twice a year.
以下に、その使用方法をステップごとに説明します。
ステップ1：クラスノートを作成する
A teacher creates one notebook per class, with a section per subject.
Students get a private area plus a shared content library.
Step 2: Build a Page Template
Build a page with headings, a table and a date field, then save it as a template.
Every new page in that section reuses the same layout.
これがその様子です。
✓ チェックポイント: The change appears on the page straight away.
Step 3: Distribute and Mark Work
Push a page to every 学生 in one click, for example a weekly worksheet.
Type feedback beside their answers and highlight the details that need work.
Students keep their own copy after the term ends, which beats loose handouts.
✅ 結果: Lesson plans, handouts and marked work sit in one notebook instead of scattered documents.
💡 プロのヒント: Ask students to tag questions with Ctrl+2. You can then pull every open question into one search view.
Microsoft OneNote のプロ向けヒントとショートカット
Industry experts lean on a handful of shortcuts that cut minutes off every session.
キーボードショートカット
| アクション | ショートカット |
|---|---|
| クイックノートを開く | Windows + N |
| Create a page in the current section | Ctrl + N |
| Search every notebook | Ctrl + E |
| Tag a line as To-Do | Ctrl + 1 |
ほとんどの人が見逃す隠れた機能
- クイックノート: Windows + N captures a thought without opening the full app. They work like sticky notes that never get lost.
- Internal wiki links: Type [[Page Title]] to create and link a page 即座に. Your notebook turns into a personal wiki.
- Password protection: Right-click any section and lock it. Useful for client data and personal records.
- Tags plus search: Tag important notes, then use Find Tags to build a live task list across all notebooks.
Microsoft OneNoteでよくある間違いとその回避方法
Mistake #1: Dumping Everything Into One Section
❌ 間違い: A shopping list, client notes and holiday plans stacked in one endless page.
✅ 右: Create a new section per area of life, then a page per topic inside it.
Mistake #2: Keeping the Notebook Only on Your Computer
❌ 間違い: Saving a local notebook to your desktop, then losing syncing across devices.
✅ 右: Store notebooks in OneDrive so every edit reaches your phone in seconds.
Mistake #3: Never Tagging Anything
❌ 間違い: Scrolling through months of notes to find one action item you wrote in a meeting.
✅ 右: Tag tasks and questions as you write, then pull them into a single searchable list.
Microsoft OneNoteのトラブルシューティング
Problem: Notes Are Not Syncing Between Devices
原因： The notebook sits offline, or you signed in with a second Microsoft account.
修理： Right-click the notebook, choose Sync This Notebook Now, and confirm the account on each device.
Offline edits queue up safely and upload the moment the computer reconnects.
Problem: Embedded Online Videos Will Not Play
原因： Old help pages still tell people to install Microsoft Silverlight, Adobe Flash Player or Internet Explorer.
修理： Ignore that advice, update OneNote instead, and paste the video link again on a clean page.
Modern browsers stream online videos natively, so no extra player is needed.
Problem: OneNote for Windows 10 Keeps Nagging You
原因： Microsoft retired OneNote for Windows 10 and moved everyone to the main desktop app.
修理： Install OneNote on Windows from the Microsoft Store, then delete the old app once syncing finishes.
Your notebooks stay in OneDrive, so nothing is lost during the move.
