ABSTRACT:
A solid electrolytic capacitor includes a capacitor element, an anode terminal, a cathode terminal, and an outer casing resin. The anode and cathode terminals constitute parts of the mounting surface, and are drawn immediately below the capacitor element. The anode terminal and the cathode terminal are electrically coupled with an anode leader of the capacitor element and a cathode layer, respectively. The outer casing resin covers the capacitor element, and exposes the anode and cathode terminals on the mounting surface. At least one recess is provided on a mounting surface side of at least one of the anode and cathode terminals having a larger area projected onto the mounting surface.
