ABSTRACT:
In this solid electrolytic capacitor, a plate-shaped anode having a porous sintered body is formed covering one part of an anode lead. A dielectric layer is formed covering the anode. An electrolyte layer of tantalum carbide is formed covering the dielectric layer. A cathode is formed covering the electrolyte layer. A conductive adhesive layer is formed on the upper surface of the cathode, and the cathode and a cathode terminal are connected by the conductive adhesive layer. An anode terminal is connected by welding the anode terminal on the anode lead projecting from the anode. Further, a mold outer resin is formed around the second conductive layer, the cathode terminal and the anode terminal.
