Abstract:
A liquid-ejecting head comprises a pressure-generating chamber and a piezoelectric element including a piezoelectric material. The piezoelectric material contains a complex oxide having a perovskite structure. The complex oxide contains bismuth, sodium, barium, titanium, and copper. The ratio of copper to the total amount of titanium and copper is 0.35 mol % or more and 0.70 mol % or less.
