Zusammenfassung:A liquid ejection head includes a plurality of ejection ports, a plurality of pressure chambers each communicating with each of the ejection ports, a piezoelectric actuator constituting part of walls of the pressure chambers, and a common liquid chamber containing liquid to be supplied to the pressure chambers. The pressure chambers and the common liquid chamber are opposed with an opposing wall interposed therebetween. The opposing wall faces the wall of the pressure chambers constituted by the piezoelectric actuator A reinforcing portion that supports the opposing wall is provided in the common liquid chamber.
