A liquid ejection head includes a housing having a first outer surface; a liquid ejection substrate disposed at a first portion of the first outer surface and having ejection ports for ejecting liquid; and a wiring member disposed on a second portion of the first outer surface so as to be next to the liquid ejection substrate and electrically connected to the liquid ejection substrate. The ejection ports are covered by a cap that is in contact with the wiring member and a portion, except the second portion, of the first outer surface around the liquid ejection substrate; and the second portion is recessed relative to the portion, except the second portion, of the first outer surface around the liquid ejection substrate.
