Abstract

A piezoelectric thin film element contains an electrode layer (first electrode layer) and a piezoelectric thin film directly or indirectly stacked on the electrode layer. The piezoelectric thin film contains a tetragonal crystalof a perovskite-type oxide and a tetragonal crystalof a perovskite-type oxide. A (001) plane of the tetragonal crystalis oriented in a normal direction of a surface of the electrode layer. A (001) plane of the tetragonal crystalis inclined with respect to the (001) plane of the tetragonal crystal. A spacing of (001) planes of the tetragonal crystalis c. A spacing of (100) planes of the tetragonal crystalis a. A spacing of (001) planes of the tetragonal crystalis c. A spacing of (100) planes of the tetragonal crystalis a. c/ais larger than c/a
