Accordingly, a manganese oxide layer 6 can be formed on the part 5 only by a thermal decomposition. As the tape 3 has a heat resistance, the tape 3 is never deteriorated in a thermal decomposition process and a conductive high-molecular layer 7 can be formed on the part 5 only by an electrolytic polymerization. Thereby, as the area of the part 5 to be used as a capacitor becomes a constant one, a solid electrolytic capacitor, which is high in the accuracy of the capacitance, can be obtained and moreover, as a possibility that the part 5 reaches up to the part 4 is also eliminated, the solid electrolytic capacitor, whose leakage current is low, can be obtained at a high yield.
