A gasket that can exhibit good heat resistance (in particular, instantaneous heat resistance), good electrolyte resistance and insulating property, and good sealing property while achieving size and thickness reduction, an enclosed secondary battery including the gasket, and an electrolytic capacitor including the gasket are achieved. The enclosed secondary battery includes a battery element 15 that includes a positive plate 11, a negative plate 12, and two separators 13 and 14 interposed between the positive plate 11 and the negative plate 12; a sealing body (positive electrode terminal) 17 electrically connected to the positive plate 11; a negative electrode terminal 18 electrically connected to the negative plate 12; and a gasket 19 for insulating the positive electrode terminal from the negative electrode terminal. The gasket 19 is a gasket containing a cross-linked ionomer and is bonded onto the positive electrode terminal or the negative electrode terminal 18 by applying heat and pressure. |
