Abstract
A method for producing a conductive polymer dispersion liquid includes preparing an emulsion of a polyanion adsorbed on a conductive polymer precursor monomer by emulsifying a blended liquid obtained by blending the conductive polymer precursor monomer, the polyanion, and an aqueous solvent; and forming a dispersoid of a conductive polymer by chemical oxidative polymerization with addition of an oxidant to the emulsion. Furthermore, by using this conductive polymer dispersion liquid to provide an electrolytic capacitor, the ESR of the capacitor can be reduced.
