US 2011/0032662 A1 · SOLID ELECTROLYTIC CAPACITOR AND A METHOD FOR MANUFACTURING THE SAME

Abstract

A solid electrolytic capacitor according to the present invention includes a solid electrolyte type capacitor element including a dielectric layer intervening between an anode section and a cathode section, an anode terminal connected electrically to the anode section of the capacitor element through a pad member, and a cathode terminal connected electrically to the cathode section of the capacitor element. Here, on facing surfaces of the pad member and the anode terminal, a joint part which joins the pad member and the anode terminal electrically is formed at a position adjacent to a first lateral surface of the pad member located on the cathode terminal side, and a second lateral surface of the pad member on the opposite side to the first lateral surface and a partial area of a lateral end surface of the anode terminal are flush with each other.
