Abstract

An electrolytic capacitor comprises an anode foil, a cathode foil, and an electrolytic paper interposed between the anode foil and cathode foil. The electrolytic paper is formed with a plurality of discontinuous projections on its one side and recesses corresponding to the projections in its other side by a secondary working step after a paper producing step. This electrolytic paper is thicker and has a low density in comparison with its non-treated state before the secondary working step.
