Abstract
In a method of manufacturing a compact and light-weight chip-type aluminum electrolytic capacitor, thin external leads are welded to flat anode and cathode foils. The anode and cathode foils are superposed with an insulating spacer interposed therebetween. The portion between the anode and cathode foils is impregnated with an electrolytic solution to obtain a capacitor element. The two surfaces of the capacitor element are covered with synthetic resin laminate films. The openings of the laminate films are welded and sealed to complete the capacitor.
