Abstract
A method for manufacturing a solid electrolytic capacitor, which includes the steps of: in a dispersion medium containing a monomer for obtaining a conjugated conductive polymer and a seed particle with protective colloid formed of a polyanion, polymerizing the monomer to obtain a conjugated conductive polymer-containing dispersion liquid; attaching the conjugated conductive polymer-containing dispersion liquid to the surface of a porous anode body at least having an anode body made of a valve metal and a dielectric film formed on the surface of the anode body; and removing a part or all of the dispersion medium from the conjugated conductive polymer-containing dispersion liquid attached to the porous anode body to form a solid electrolyte layer. Also disclosed is a solid electrolytic capacitor obtained by the method.
