Beschreibung
Zusammenfassung:	A liquid ejecting head includes a diaphragm that constitutes a part of a wall surface of a pressure chamber in which a liquid is filled, and a piezoelectric element that vibrates the diaphragm, in which the piezoelectric element includes a first electrode and a second electrode, and a piezoelectric layer including a first portion located between the first electrode and the second electrode and a second portion not overlapping at least one of the first electrode and the second electrode in plan view, a first surface at an opposite side of the first portion from the diaphragm and a second surface at an opposite side of the second portion from the diaphragm are different in position in a laminate direction of the first electrode, the piezoelectric layer, and the second electrode, and a second film thickness of the second portion is larger than a first film thickness of the first portion.
