Abstract
The invention relates to a process for producing a solid electrolytic capacitor element, comprising forming a semiconductor layer containing a conductive polymer on a conductor having a dielectric layer on its surface. By using the solid electrolytic capacitor element of the invention prepared by forming a semiconductor layer on the conductor having a dielectric layer on its surface by an electrification method after the conductor is impregnated with a dopant, a solid electrolytic capacitor having a favorable ESR value can be fabricated.
