Patent ID: 7394649

Claim:
A solid electrolytic capacitor comprising: a capacitor element including: an anode body made of a valve metal, and having an anode leader provided at one end thereof; a dielectric oxide film formed on a surface of the anode body on a side opposite a side on which the anode leader is provided; a solid electrolyte formed on the dielectric oxide film; and a cathode layer formed on the solid electrolyte; an anode terminal electrically coupled with the anode leader, the anode terminal being drawn immediately below the capacitor element to constitute a part of a mounting surface; a cathode terminal electrically coupled with the cathode layer, the cathode terminal being drawn immediately below the capacitor element to constitute a part of the mounting surface; and an outer casing resin covering the capacitor element so as to expose the anode terminal and the cathode terminal on the mounting surface; wherein one of the anode terminal and the cathode terminal has an area projected onto the mounting surface that is larger than an area of the other of the anode terminal and the cathode terminal projected onto the mounting surface; wherein at least said one of the anode terminal and the cathode terminal that has the larger area projected onto the mounting surface is provided on the mounting surface side with at least one recess; and wherein parts of a metal wall surface of said at least one recess are exposed from said outer casing resin, and raised spots are formed by laser irradiation on the parts of the metal wall surface of said at least one recess that are exposed from said outer casing resin.
