Abstract
A method for manufacturing a capacitor that enables a capacitor having a high degree of conductivity and minimal leakage current to be obtained with a high level of productivity. A method for manufacturing a capacitor () according to the present invention includes an electrolytic oxidation step of forming a dielectric layer () by electrolytically oxidizing the surface of an anode () composed of a valve metal, a cathode positioning step of positioning a cathode () composed of a conductor in an opposing arrangement on the surface of the dielectric layer (), a solid electrolyte formation step of forming a solid electrolyte layer () between the dielectric layer () and the cathode () using a conductive polymer solution containing a π-conjugated conductive polymer and a polyanion, and an application step of performing a treatment in which a direct current voltage is applied between the anode () and the cathode ().
