In a solid electrolytic capacitor which employs a conducting polymer as the solid electrolyte, a first solid electrolytic layer (3) consisting of a sole conducting polymer is formed by chemical polymerization on an oxide film (2) formed on the surface of an anode body (1). Next, a second solid electrolytic layer (4) consisting of a conducting polymer containing fine powder, obtained by chemical polymerization using a solution in which fine powder is dispersed in a reaction solution for chemical polymerization, is formed on the first solid electrolytic layer (3). The fine powder is harder than the conducting polymer. With this arrangement, it is possible to prevent the application of a stress to the oxide film (2) by the solid electrolytic layer (4) consisting of a conducting polymer containing fine powder even if there is generated a stress at the time of curing of a molded resin (8).
