Abstract
A solid electrolytic capacitor that includes a laminated body, a solid electrolyte layer, and conductive bases. The laminated body is obtained by laminating a plurality of dielectric-coated valve action metal sheets, each of which includes a valve action metal base and a dielectric coating, and joining together the adjacent valve action metal bases. The valve action metal base has a cathode layer part, and the dielectric coating covers the surface of the valve action metal base at least the cathode layer part. The valve action metal base of at least one of the dielectric-coated valve action metal sheets further has an anode lead part. The solid electrolyte layer is a continuous layer that fills gaps between the dielectric-coated valve action metal sheets and covers the outer surface of the laminated body at the cathode layer parts, and conductive bases are provided in the solid electrolyte layer.
