Abstract: The present disclosure provides a pressure-sensitive element having a relatively wide pressing force measurement range and a relatively simple structure. Pressure-sensitive element is provided with pressure-sensitive part that receives pressing force and detector that detects the pressing force, and has a structure described below. That is, pressure-sensitive part has first conductive member that has elasticity, second conductive member, and dielectric body. Dielectric body is disposed between first conductive member and second conductive member, and at least partially covers the surface of first conductive member or second conductive member. Detector detects pressing force based on a variation in electrostatic capacitance between first conductive member and second conductive member.
