Abstract
A solid electrolytic capacitor includes a capacitor element, an anode lead frame, a cathode lead frame, and a mold resin portion. The anode lead frame includes an anode terminal portion and a rising portion. The rising portion is formed integral with the anode terminal portion, extends from the anode terminal portion through the mold resin and is connected to an anode portion. At the rising portion, a catching portion receiving and supporting the anode portion from below and a hook portion surrounding and holding an outer circumferential surface of the anode portion, with the anode portion received in the catching portion, are formed. Therefore, a solid electrolytic capacitor can be provided, which allows highly accurate attachment of the capacitor element on the lead frame without applying any additional member and reduces equivalent series resistance.
