Abstract:
A liquid ejecting head includes a pressure generating chamber communicating with a nozzle for ejecting liquid droplets and a piezoelectric element having a piezoelectric layer and a pair of electrodes disposed on both sides of the piezoelectric layer. The piezoelectric layer is made of a perovskite-type oxide containing barium titanate, calcium titanate, and europium oxide.
