教授への英語メールの書き方｜そのまま使える例文7つ

最終更新: 2026年9月28日

アメリカの大学では、分からないことや困ったことがあれば、自分から教授にメールするのが普通です。 丁寧すぎる必要はありませんが、件名・宛名・用件・名前がそろっていないと、読まれずに後回しにされることがあります。 よく使う場面ごとに、そのまま使える例文をまとめました。[ ] の部分を書き換えてください。

基本の形

件名には授業名とセクション番号を入れます。教授は複数の授業を持っているので、どの授業の学生かがすぐ分かるようにするためです。 宛名は、シラバスにある呼び方（Professor / Dr. + 名字）に合わせます。迷ったら Professor [名字] で問題ありません。 送る前に、シラバスに答えが書いていないかを確認すると印象が良くなります。
