PRESSURE SENSOR AND ELECTRONIC DEVICE

Provided is a pressure sensor with which it is possible, without forming a physical switch, to detect a pressing operation received at a location other than the front surface of a touch panel. The pressure sensor is provided with: a piezoelectric film (10) which is bonded to a panel (101), including a flat surface portion (105) and a curved portion (106), continuously over the flat surface portion (105) and the curved portion (106), and which provides different outputs when the flat surface portion (105) has received a pressing operation and when a casing (102) connected to the curved portion (106) has received a pressing operation; and a first electrode (11) and a second electrode (12) formed on both main surfaces of the piezoelectric film (10).
