Patent ID: 8470389

Claim:
A method of manufacturing a solid electrolytic capacitor, comprising the steps of: forming a capacitor element including an anode body having a dielectric coating film on a surface thereof; impregnating the capacitor element with a polymerization liquid containing a precursor monomer of a conductive polymer and an oxidant; impregnating the capacitor element impregnated with said polymerization liquid with a silane compound or a silane compound containing solution; and forming a conductive polymer layer by polymerization the precursor monomer after impregnating the capacitor element with the silane compound or the silane compound containing solution wherein the capacitor element is formed by winding the anode body and a cathode body, the concentration of the silane compound in the conductive polymer layer formed between the anode body and the cathode body is lower than the concentration of the silane compound in the conductive polymer layer formed on an outer peripheral side of the capacitor element.
