摘要：

A piezoelectric element includes a vibrating film, a piezoelectric body, a first electrode, a second electrode, and a groove. The piezoelectric body is arranged upon the vibrating film. The first electrode is arranged upon the piezoelectric body. The second electrode is arranged upon the piezoelectric body and at a position that is separated from the first electrode. The groove is located between the first electrode and the second electrode and splits a surface of the piezoelectric body in two, as seen in plan view from a thickness direction of the vibrating film.
