Liquid ejecting head, liquid ejecting apparatus, and piezoelectric element

摘要

A liquid ejecting head includes a pressure generating chamber communicating with a nozzle aperture, and a piezoelectric element. The piezoelectric element includes a first electrode (60) made of platinum, a piezoelectric layer (70) on the first electrode, made of a complex oxide having a perovskite structure containing at least bismuth, and a second electrode (80) on the piezoelectric layer. An oxide (65) containing bismuth and platinum is disposed at the interface of the piezoelectric layer (70) with the first electrode (60).
