Abstract
A solid electrolytic capacitor is made of a first chemical polymer layer having an anode, a cathode, and a dielectric, the cathode being formed first on a surface of the dielectric, and a secondary electrolytic polymer layer formed on a surface of the primary chemical polymer layer by performing electrolytic polymerization in a predetermined solution. This solid electrolytic capacitor includes a secondary electrolytic polymer layer formed by performing electrolytic polymerization in a solution obtained by adding to the predetermined solution a supporting electrolyte having a surface active effect with respect to a solvent in the predetermined solution and a supporting electrolyte having no surface active effect with respect to the solvent in the predetermined solution.
