Abstract:
1. A solid electrolytic capacitor comprising: a capacitor element including a porous sintered compact made of a valve action metal and having an anode lead, and wherein a dielectric, an electrolyte layer and a cathode layer are successively formed on a surface of the porous sintered compact; an anode terminal connected to the anode lead of said capacitor element; a cathode terminal connected to the cathode layer; and a casing material covering said terminals and said capacitor element; wherein: said anode terminal includes a first plate piece having first and second ends, a second plate piece having third and fourth ends, and a third plate piece having fifth and sixth ends, said first, second and third plate pieces are formed of continuous members, said first and said second plate pieces are placed at an interior of said casing material, said second and said third plate pieces are folded onto each other so as to be formed integrally, said third plate piece includes (i) a first surface exposed to an exterior of said casing material which forms a mounting surface defined by said the fifth and sixth ends and (ii) a second surface opposing the exposed surface, said first end of said first plate piece is arranged one of adjacent to and abutting said second surface so as to intersect to form a T shape, said second end of said first plate piece is extended and joined to the anode lead, and said first end and the fourth end are respectively connected to the third end and the fifth end.
