PROBLEM TO BE SOLVED: To provide a pressure sensitive element capable of satisfactorily reducing variation in depression sensitivity at a depressed position with a simple structure.SOLUTION: The pressure sensitive element includes: a thin wire 10 constituted of a first electrode 1 and a dielectric body 2 being laminated each other; a unit structure 110 which is configured of the thin wire being combined in a plane; a planar element 210 which is constituted of plural unit structures being arranged in a plane; and a second electrode member 3 which includes a conductivity member 32 disposed at the dielectric body of the planar element being faced to a first plane 320. When a pressing force is applied to the first electrode 1 and the second electrode member 3 therebetween from the outside, the electrostatic capacitance therebetween the electrodes changes.SELECTED DRAWING: Figure 1 【課題】簡便な構成で、押圧位置による押圧感度のバラツキをより十分に低減できる感圧素子を提供すること。【解決手段】第１の電極１と誘電体２とが積層されて構成された細線１０と、該細線が平面状に組み合わされて構成された単位構造１１０と、複数の該単位構造が平面状に配置されて構成された面状素子２１０と、該面状素子の前記誘電体の側に第１の面３２０を対向させて設けられた導電性部材３２を含む第２の電極部材３と、を備え、前記第１の電極１と前記第２の電極部材３との間に外部から押圧力が加えられることによって、これらの電極間の静電容量が変化する感圧素子。【選択図】図１
