Abstract

Provided is pressure sensor capable of accurately detecting pressure applied to an object from the outside as a surface and the like. The pressure sensor includes: a plurality of sensor pixels PX arranged in a planar pattern, each sensor pixel PX including a film-like pressure-sensitive film 2 of which a resistance value changes when pressed from a front surface and a first electrode layer 4 and a second electrode layer 6 laminated only on a rear surface of the pressure-sensitive film 2; and a drive circuit that drives each sensor pixel PX, the drive circuit detecting pressure of pressing applied to the plurality of sensor pixels PX for each sensor pixel PX based on a change in the resistance value caused by the pressing.
