Abstract:
A liquid ejecting head includes a flow channel substrate and piezoelectric elements, with a diaphragm between the piezoelectric elements and the flow channel substrate. The flow channel substrate has pressure chambers lined up in a first direction with walls therebetween. Each piezoelectric element includes a first electrode, a piezoelectric layer and a second electrode. Each piezoelectric element has a piezoelectrically active portion, a region in which the piezoelectric layer is sandwiched between the first electrode and the second electrode, and are provided in regions facing the pressure chambers. The liquid ejecting head further includes holding members joined the diaphragm facing the walls using an adhesive agent. The width of the holding members is equivalent to or larger than the width of the walls. The width of an adhesive agent with which the holding members are joined to the diaphragm is equal to or smaller than the width of the walls.
