ABSTRACT:
An anode foil, a cathode foil and a separator therebetween are rolled up into a capacitor element, and driving electrolyte is impregnated into the capacitor element. The capacitor element is housed in a metal case 12, and its opening is sealed by a sealer 13. The metal case 12 is made of an alloy of aluminum and manganese. Since this alloy has the higher hardness than that of a conventional case, the case is hard to be deformed even the capacitor is left in a high temperature atmosphere.
