ABSTRACT:
Disclosed is a solid electrolytic capacitor, wherein a capacitor element has a front surface from which an anode lead wire is protruded. A cathode layer is formed on an outer surface of the capacitor element. A flat-shaped cathode lead frame is surface-contacted with an entire rear surface of the capacitor element. A flat-shaped anode lead frame has a concave portion formed at a central end portion thereof, in which the anode lead wire of the capacitor element is seated and electrically connected to the concave portion. A mold is formed to surround the capacitor element, to partially surround the anode lead frame, and to contact a face of the cathode lead frame which is surface-contacted with the capacitor element.
