ABSTRACT:
An aluminum electrolytic capacitor has a large cylindrical hole in a core portion thereof. The anode and cathode foils and electrolyte-containing papers are rolled with less tension for an initial predetermined number of turns than for the later turns. Instead of forming the hole large, a core portion is formed by rolling the electrolyte-containing papers and either the anode foil or the cathode foil, or neither of them.
