A cathode foil and an anode foil, with an oxidized film layer formed on the surface and a separator interposed therebetween, are wound together to form a capacitor element, and prior to subjecting the capacitor element to chemical repair the content of the binder in the separator is adjusted to 10 to 20% with respect to the total weight of the separator. After the chemical repair, the capacitor element is immersed in mixed liquid prepared by mixing a polymerizable monomer and an oxidizing agent together with a predetermined solvent, a polymerization reaction of the electroconductive polymer is induced in the capacitor element, and a solid electrolyte layer is formed. The capacitor element is then inserted in an outer case; sealing rubber is mounted in the open-end portion and sealed with a tightening operation; and the unit is thereafter aged to form a solid electrolytic capacitor.
A solid electrolytic capacitor comprising a capacitor element having an anode foil and a cathode foil wound with a separator interposed therebetween, the capacitor element being provided with a solid electrolyte layer of an electroconductive polymer by impregnating the capacitor element with a polymerizable monomer and an oxidizing agent,
