PURPOSE:To uniformize the length of a fuse even if there is an irregularity in soldering amounts by sequentially forming a first insulating layer and a conductive layer on the end surface of a cathode lead, and exposing the surface with the partial surface of the conductive layer to form a second insulating layer. CONSTITUTION:Sheath resin 6 which covers a capacitor element 1 and the connection sections of electrode leads 2 of the element 1 thereto is provided. It has a first insulating layer 7 formed on the surface of the end of at least one lead 2, a conductive layer 8 formed by covering the layer 7 and electrically connecting to the lead 2, and a second insulating layer 9 provided by covering the surface of the layer 8 except a part, and a part of the layer 8 is electrically connected to the electrode 1 of the element. Thus, even if solder amounts and soldering positions are irregular, the length of a fuse 8C can always be maintained constant, it can be fused by a constant current to prevent the capacitor from burning.
