Abstract:
A liquid ejection head includes a plurality of ejection orifices which eject a liquid, a plurality of pressure chambers which store the liquid ejected from the ejection orifices and eject the liquid from the ejection orifices in accordance with expansion and contraction of an inner wall of the pressure chambers, and a plurality of recess portions which are formed around the pressure chambers, wherein a piezoelectric member is present between at least one of the recess portions and the pressure chambers.
