Abstract
A method for producing a solid electrolytic capacitor, involving a step of loading a metal oxide on at least a part of the surface in the anode part of a capacitor element having a valve-acting metal substrate having there on a solid electrolyte, the valve-acting metal substrate having a dielectric film obtained by the electrochemical forming, and a solid electrolytic capacitor obtained by stacking two or more single plate capacitor elements having a metal oxide on at least a part of the surface in the anode part of a capacitor element comprising a valve-acting metal substrate having thereon a solid electrolyte, the valve-acting metal substrate having a dielectric film obtained by the electrochemical forming.
