ABSTRACT:
In a solid electrolytic capacitor of the present invention, a virtually plate-like anode having a porous sintered body, a dielectric layer, and an electrolyte layer are sequentially formed on an anode lead so as to cover a portion of the anode lead. A cathode includes a first electrically conductive layer containing graphite particles having a grain size of approximately 1 μm to approximately 10 μm and APTES; and a second electrically conductive layer including silver particles is formed on the electrolyte layer so as to cover an area surrounding the electrolyte layer. Also, the cathode and a cathode terminal are interconnected through an electrically conductive adhesive layer, and the anode lead and an anode terminal are welded to each other. Further, a mold-packaging resin is formed such that respective edges of the cathode terminal and the anode terminal are located outside the mold-packaging resin.
