Abstract: Provided is a pressure-sensitive element having a relatively wide measurement range of a pressing force and a relatively simple structure while having more sufficient stretchability. A pressure-sensitive element includes a base material, a plurality of conductor wires, a plurality of dielectrics, and a filamentous member. The base material includes an elastic conductor having elasticity and conductivity. Further, the base material has a sheet shape. The plurality of conductor wires are arranged in parallel so as to individually intersect with the elastic conductor in plan view. Further, each of the plurality of conductor wires has a plurality of inflection parts. The plurality of dielectrics are arranged between the elastic conductor and the plurality of conductor wires. The filamentous member elongates so as to intersect with the plurality of conductor wires in plan view. Further, the filamentous member sews the plurality of conductor wires to the base material.

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.
