Piezoelectric element, liquid ejecting head, and liquid ejecting apparatus

Abstract

A piezoelectric element includes: a lower electrode; a piezoelectric body; and an upper electrode, in which the piezoelectric body has a perovskite structure that includes at least K, Na, and Mn in an A-site and includes at least Nb and Mn in a B-site. In addition, a liquid ejecting head includes: a piezoelectric element; a pressure chamber in which liquid is flowed to apply a pressure to the liquid by the piezoelectric element; and a nozzle configured to eject the liquid using the pressure applied in the pressure chamber. In addition, a liquid ejecting apparatus includes: a liquid ejecting head; and a voltage application circuit configured to control driving of the piezoelectric element such that the liquid is ejected from the nozzle.
