Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power storage element capable of easily and surely detecting another object when external force due to another object acts.SOLUTION: A power storage element includes: an electrode body; and a case in which the electrode body is housed. A first conductor layer, a second conductor layer laminated on the first conductor layer, and an insulating layer interposed between the first conductor layer and the second conductor layer are arranged in the case. The first conductor layer or the second conductor layer has a plurality of projections on the surface opposite to the insulating layer, and voids are formed in the region between the plurality of projections.SELECTED DRAWING: Figure 5 【課題】本発明は、他物体による外力が作用した場合にこの他物体を容易かつ確実に検出することができる蓄電素子を提供することを課題とする。【解決手段】本発明に係る蓄電素子は、電極体と、この電極体を収容するケースとを備え、上記ケースに、第１導体層と、この第１導体層に積層される第２導体層と、この第１導体層及び第２導体層の間に介在する絶縁層とが配され、上記第１導体層又は第２導体層が上記絶縁層と対向する面に複数の突起を有し、上記複数の突起間の領域に空隙が形成されている。【選択図】図５
