Abstract:
A pressure-sensitive element of the present disclosure includes a substrate, a conductive component, an elastic electrode portion, and an electrode supporting component. The conductive component extends from the substrate. The elastic electrode portion opposes a tip of the conductive component. The electrode supporting component opposes the substrate with the conductive component and the elastic electrode portion interposed therebetween, supports the elastic electrode portion, and has flexibility. In the pressure-sensitive element, the conductive component has a higher elastic modulus than that of the elastic electrode portion. In the pressure-sensitive element, the elastic electrode portion has a flat surface which opposes the conductive component and which is capable of being brought into contact with the conductive component.

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.
