Abstract
A liquid ejection head includes a recording element substrate for ejecting liquid in response to an externally supplied electrical signal; an electrical wiring board having a first and second part mutually joined via a bent portion, the first part having an electrical joint portion for supplying the signal to the substrate, the second part having an electrical signal input portion into which the signal is input and to which the joint portion is connected; and a housing having first and second surfaces mutually adjoining, the first and second surfaces respectively supporting the first and second parts. The second part is fixed to the second surface at plural first fixing positions around the input portion. The second surface has a depressed portion formed closer to the bent portion than the first fixing positions. The second part is fixed to the housing at a second fixing position inside the depressed portion.
