Claim 0:
1. A capacitor comprising
i) an electrode body comprising an electrode material, wherein a dielectric layer comprising a dielectric material at least partially covers a surface of the electrode body;
ii) a solid electrolyte layer comprising a solid electrolyte material that at least partially covers a surface of the dielectric layer, wherein the solid electrolyte material comprises a conductive polymer;
iii) an anode contact that is in contact with the electrode body and that comprises copper, metal-plated copper or a copper-containing alloy; and
iv) a cathode contact that is in contact with the solid electrolyte layer;, wherein the capacitor further comprises at least one metal ion migration inhibitor being able to form a chelate-complex with copper ions, wherein the at least one metal ion migration inhibitor is localized within the solid electrolyte layer or is localized on the surface of the solid electrolyte layer.
