Abstract: A liquid ejection head includes an ejection element substrate, an electrical contact portion, a housing, and an opening/closing member. The ejection element substrate ejects liquid to perform recording. The electrical contact portion is electrically connected to an electrical wiring unit of an ejection apparatus to supply power to the ejection element substrate. The housing includes an opening portion into which the electrical wiring unit is inserted and to be provided with the electrical contact portion inside. The opening/closing member opens and closes the opening portion. In a closed state in which the opening/closing member closes the opening portion, the electrical wiring unit is sandwiched between the opening/closing member and a part of the housing.

Abstract: A liquid discharge head includes a liquid discharge unit, a housing, an electrical connection portion, and a connection portion cover member. The liquid discharge unit discharges liquid, the housing covers the liquid discharge unit, and the electrical connection portion is electrically connected to an electrical wiring substrate of a recording apparatus. The connection portion cover member covers the electrical connection portion. Power is supplied from the recording apparatus to the liquid discharge unit via the electrical connection portion. The housing includes a recessed portion into which the connection portion cover member is to be inserted. The connection portion cover member includes an insertion portion insertable into the recessed portion. The insertion portion is covered by the recessed portion.
