Piezoelectric element, piezoelectric actuator, liquid ejecting head, liquid ejecting apparatus, and method for producing piezoelectric element

摘要

A piezoelectric element includes a substrate; a first conductive layer disposed on or above the substrate; a piezoelectric layer covering a top and a side of the first conductive layer; a relaxing layer disposed on or above the piezoelectric layer and along an edge of a top surface of the piezoelectric layer; and a second conductive layer covering at least the relaxing layer and the piezoelectric layer.
