Abstract:
A liquid ejecting head includes a pressure generating chamber communicating with a nozzle aperture, and a piezoelectric element including a piezoelectric layer and electrodes that apply a voltage to the piezoelectric layer. The piezoelectric layer is made of a complex oxide having a perovskite structure. The piezoelectric layer contains bismuth, barium, iron and titanium. The piezoelectric layer has an intensity ratio of a (111) orientation intensity to a (100) orientation intensity of 3 or more.
