A pressure sensor that includes a piezoelectric film having a flat part and a curved part and having opposed first and second main surfaces, a first electrode on the first main surface of the piezoelectric film, and a second electrode on the second main surfaces of the piezoelectric film. When the flat part of the piezoelectric film receives a pressing operation a first output is generated, and when the curved part of the piezoelectric film receives a pressing operation a second output different from the first output is generated.
