In an electrical junction box, a first board part and a second board part are arranged substantially in parallel while opposing to each other. An electric wire extends along both of the first board part and the second board part, and has a bent portion extending across a gap defined between the first board part and the second board part. An electronic unit is disposed in the gap.
