noun
home telephone; home phone number
Slang term for a landline or home phone number, often contrasted with a mobile phone (ケータイ). Used in casual conversation.
家電にかけてみたけど、誰も出なかった。
I tried calling the home phone, but nobody answered.
履歴書には家電の番号も書いておいた。
I also wrote down my home phone number on the resume.
Abbreviation of 家の電話 (いえのでんわ, 'home telephone'). The reading いえでん comes from the first two characters of 家電, but note that the same kanji are also used for かでん (home appliances), which is a separate word.
