摘要:
A solid electrolytic capacitor includes a porous sintered body made of a valve-acting metal and embedded with part of an anode lead having a protruding portion, a solid electrolyte layer formed in contact with a dielectric layer formed in the porous sintered body, a mounting anode terminal member, a mounting cathode terminal member, and an insulating casing resin. The capacitor further includes a small piece of a metal frame made of a valve-acting metal. This small piece of the metal frame is formed integrally with the protruding portion of the anode lead by cutting, after the anodic oxidation, the metal frame to which the protruding portion of the anode lead is fixed by resistance welding. The small piece of the metal frame and the mounting anode terminal member are connected together by wire bonding so that the anode lead and the mounting anode terminal member are electrically connected together.
