PIEZOELECTRIC ELEMENT, LIQUID EJECTING HEAD, AND LIQUID EJECTING APPARATUS

摘要

A piezoelectric element comprises a piezoelectric layer and an electrode provided to the piezoelectric layer. The piezoelectric layer is made of complex oxide having a Perovskite-type structure containing bismuth and iron, and the complex oxide includes at least one kind of a first doping element selected from the group consisting of sodium, potassium, calcium, strontium and barium and a second doping element formed from cerium.
