サ。[Scope of Claim for Utility Model Registration] (1) A capacitor element is housed in a cylindrical metal case with a bottom, and a through hole in the opening of the case and a valve member that elastically fits into the through hole. In an electrolytic capacitor equipped with a sealing plate having a safety device, the valve member has a valve head having a substantially larger diameter than the through hole, and a valve head having a substantially smaller diameter than the through hole, and one end of which has a valve head having a substantially larger diameter than the through hole. An electrolytic capacitor comprising: a valve stem connected to a valve head; and a stopper formed at the other end of the valve stem to prevent the through hole from coming off. (2) The electrolytic capacitor according to claim 1, wherein the axial length of the valve stem is longer than the axial length of the through hole. (3) The electrolytic capacitor according to claim 1, wherein the stopper has a plurality of legs extending radially from the other end of the valve shaft. (4) The electrolytic capacitor according to claim 3, wherein the legs intersect at right angles to the axis of the valve stem. (5) The electrolytic capacitor according to claim 3, wherein the leg intersects the axis of the valve shaft at an acute angle. (6) The electrolytic capacitor according to claim 1, wherein the valve member is fitted into the through hole from the valve head side from the back side of the sealing plate. (7) The electrolytic capacitor according to claim 1, wherein the valve member is fitted into the through hole from the stopper side thereof from the surface side of the sealing plate.
