PROBLEM TO BE SOLVED: To provide an aluminum electrolytic capacitor in which, when the pressure of the inside of a case increases to problematic pressure, an explosion-proof function rapidly works.SOLUTION: The aluminum electrolytic capacitor has a structure in which a capacitor element is housed in a case having a groove-like explosion-proof valve formed on the side surface and the outer side surface of the case is covered with a thermal shrinkable tube where the thermal shrinkable tube has a slit having a round or square end. |
