Abstract:
A liquid ejecting head including a piezoelectric element, the piezoelectric element includes: a first electrode; an orientation control layer provided on the first electrode, the orientation control layer having a perovskite structure including Bi in an A site and Fe and Ti in a B site, and the orientation control layer being self-oriented in a (100) plane; a piezoelectric body layer provided on the orientation control layer and made of a piezoelectric material of the perovskite structure preferentially oriented in the (100) plane; and a second electrode provided on the piezoelectric body layer.
