Abstract

Solid electrolyte capacitors are produced in such a way that a formed metallic anode body which has pores passing through it is arranged on a working electrode, and a conductive polymer is deposited in the pores of the anode body by electochemical polymerization of a monomer in the liquid phase, in the presence of a conducting salt. The polymer is provided with a contact point.
