Abstract

Method of manufacturing an anode for an electrolytic capacitor by sintering compressed powder of a film-forming metal, to which is added an auxiliary substance that disappears during the treatment and as a result of this increases the porosity, and anodic oxidation of the sintered body, characterized in that naphthalene is used as the auxiliary substance.
