ABSTRACT:
A solid electrolytic capacitor of the type having a built-in fuse is disclosed in which a connecting portion between the fuse and a capacitor element is made thin and securely formed to accommodate the capacitor element to be increased in capacitance without changing the outer size of a resin package. The solid electrolytic capacitor including a capacitor element, an internal anode lead extending from one surface of the capacitor element, other surfaces of the capacitor element serving as a cathode terminal wall, an external anode lead connected to the internal anode lead, an external cathode lead connected to the cathode terminal wall through a fuse, and a resin package encapsulating the capacitor element, the fuse and respective connecting portions of the external anode lead and the external cathode lead. A connecting portion between the fuse and one end of the external cathode lead lies adjacent the capacitor element and in or out of a plane coplanar with the surface of the cathode terminal wall to which the fuse is pressure-welded.
