Claim 12:
13. The method for manufacturing a hybrid electrolytic capacitor according to claim 12,
wherein the cathode substrate has an etching pit, and, in the cathode formation process, a slurry containing carbon particles is applied to the surface of the oxide layer on the cathode substrate and dried to obtain a slurry layer and then the slurry layer is subjected to press to push the carbon particles into the etching pit and to make the carbon particles penetrate through the oxide layer and conduct with the cathode substrate to form a carbon coating layer having an entry area entering the etching pit and a penetration area penetrating through the oxide layer and conducting with the cathode substrate as the inorganic conductive layer.
