    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: Provided is a pressure-sensitive element having more sufficient expandability, a relatively wide measurement range of pressure force, and a relatively simple structure, and an electronic device using the pressure-sensitive element. The pressure-sensitive element includes a plurality of first electrodes being elongated in first direction, arranged in a first plane, and including a conductive elastic body, a plurality of second electrodes being elongated in second direction intersecting the first direction, arranged in a second plane facing the first plane, and including a conductor wire, and a plurality of dielectrics covering a surface of the plurality of second electrodes. The plurality of second electrodes have bent parts K arranged periodically, and capacitance at intersections of the plurality of first electrodes and the plurality of second electrodes changes in accordance with pressure force applied between the plurality of first electrodes and the plurality of second electrodes.
