Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor with smaller equivalent series resistance (ESR).SOLUTION: In a solid electrolytic capacitor (20), laminated are a plurality of dielectric coating valve action metal sheets (4) including a valve action metal base (1) with a cathode layer formation part (1b), and a dielectric film (3) coating the surface of the valve action metal base (1) at least in the cathode layer formation part (1b); the valve action metal base (1) included in at least one of dielectric coating valve action metal sheets (4) has further an anode lead part (1a); provided are a laminate (5) with adjacent valve action metal bases (1) mutually joined, a continuous layer of a solid electrolyte layer (7) for filling spaces between the dielectric coating valve action metal sheets (4) and coating an external surface of the laminate (5) in the cathode layer formation part (1b) of the valve action metal base (1), and a conductive base (9) disposed in the solid electrolyte layer (7) for filling the spaces between the dielectric coating valve action metal sheets (4).
