An electronic device that includes a housing and a piezoelectric sensor. The piezoelectric sensor is disposed in contact with an inner wall surface of the housing while in a bent state. The piezoelectric sensor includes a piezoelectric film, a coverlay, a first electrode, a second electrode, a third electrode, and a substrate having flexibility. The first electrode is disposed on a surface of the substrate. The first electrode includes a wide part and a narrow part. The coverlay covers a boundary between the wide part and the narrow part. The piezoelectric film covers a boundary between a part of the first electrode which is covered with the coverlay and a part of the first electrode which is not covered with the coverlay.
