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, and the anode terminal portion is exposed at the bottom surface of the mold resin portion. The rising portion is formed integral with the anode terminal portion, and rises to the anode portion. In the rising portion, a through hole is formed. The cathode lead frame includes a cathode terminal portion, a pair of side surface portions and a step portion. Thus, a solid electrolytic capacitor allowing highly accurate and reliable attachment of the capacitor element to the lead frame without using any additional member is provided.

Solid electrolytic capacitor

A solid electrolytic capacitor includes a capacitor element from which an anode lead projects forward and having a surface on which a cathode layer is formed, an exterior resin covering the capacitor element, and anode and cathode terminals including, respectively, an anode and cathode terminal surfaces which are exposed from a bottom surface of the exterior resin. The anode terminal is formed from one metal plate, and includes a terminal part forming the anode terminal surface, a folded part folded back at a side edge of the terminal part and arranged over a top surface of the terminal part, and an upright part bent vertically to the top surface of the terminal part at a front edge or a rear edge of a tip end part of the folded part. A tip end part of the anode lead is electrically connected to a tip end of the upright part.
