Abstract
In a solid electrolytic capacitor including a porous valve-acting metal, an anode conductor has a large number of pores having openings on the surface thereof according to the porosity of the valve-acting metal. A solid electrolyte layer is formed on the surface of the anode conductor so as to be filled in at least a portion of each of the pores and to close the openings thereof. Further, a cathode conductor is formed on the solid electrolyte layer. Preferably, the solid electrolyte layer has a two-layer structure with two layers having different particle sizes.
