摘要

PCT No. PCT/JP88/00757 Sec. 371 Date Mar. 29, 1989 Sec. 102(e) Date Mar. 29, 1989 PCT Filed Jul. 28, 1988 PCT Pub. No. WO89/01230 PCT Pub. Date Feb. 9, 1989.The present invention is an electrolytic capacitor comprising a titanium-deposited aluminum foil used as the cathode. An aluminum foil is subjected to vacuum deposition of titanium with a deposition angle, thereby obtaining an electrolytic capacitor having a larger electrostatic capacitance than the conventional.
