PROBLEM TO BE SOLVED: To stably manufacture a solid electrolytic capacitor with excellent leak current characteristic, when the solid electrolytic capacitor having a solid electrolyte layer containing an electrically conductive polymer layer formed by electrolytic oxidative polymerization is manufactured on an industrial scale. SOLUTION: A method for manufacturing the solid electrolytic capacitor having the solid electrolyte layer containing the electrically conductive polymer layer formed by the electrolytic oxidative polymerization includes: forming a dielectric layer on a surface of an anode element containing a valve metal; forming an electrically conductive precoat layer on the dielectric layer; and performing electrolytic oxidative polymerization in an electrolytic polymerization solution containing a monomer, a dopant agent and a chelating agent to form the electrically conductive polymer layer on the electrically conductive precoat layer.
