[PROBLEMS] To provide a solid electrolytic capacitor having an excellent ESR characteristic, in which a dense solid electrolyte layer can be formed by a chemical polymerization method. [MEANS FOR SOLVING PROBLEMS] A solid electrolytic capacitor ( 1 ) is prepared by carbonizing a wound element ( 21 ) formed by winding an anode foil ( 22 ) and a cathode foil ( 23 ) together with a separator paper ( 4 ) sandwiched therebetween, and forming a solid electrolyte layer, including said separator ( 4 ), comprising a conductive polymer between the anode foil ( 22 ) and the cathode foil ( 23 ). the separator paper ( 4 ) is paper prepared by mixing fibers having low heat resistance and carbonized by said carbonizing, and fibers having high heat resistance not carbonized by said carbonizing, and fibrillated fibers having narrow spaces between fibers are used as said fibers having high heat resistance. |
