Abstract
A pressure sensor that includes a piezoelectric film having a first main surface and a second main surface, a first electrode on the first main surface of the piezoelectric film, and a second electrode on the second main surface of the piezoelectric film. At least one of the first electrode and the second electrode is formed of a material having an elastic modulus of 60 GPa or more, and the product of a thickness of the at least one of the first electrode and the second electrode in a stacking direction of the pressure sensor multiplied by an elastic modulus of the at least one of the first electrode and the second electrode is 4 MPa·m or more.
