PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor having good leakage current characteristics. SOLUTION: A method of manufacturing the solid electrolytic capacitor includes steps of: performing restoration and formation of a capacitor element in which an anode electrode foil and a cathode electrode foil are wound through a separator; impregnating with a 3, 4-ethylenedioxythiophene and an oxidizing agent solution; generating a polyethylenedioxythiophene in the capacitor element by a chemical polymerization; and then housing the capacitor element in a sheathing case. In the method, after the capacitor element performs the restoration and the formation, the capacitor element is immersed in a boric acid compound solution, heated and again subjected to the restoration and the formation. Accordingly, the leakage current characteristics are improved. COPYRIGHT: (C)2005,JPO&NCIPI
