PROBLEM TO BE SOLVED: To provide a high reliability low-cost aluminum electrolytic capacitor, wherein its heat-generation and temperature-rise occurring in its using state are suppressed and its vibration resistance is made excellent. SOLUTION: In the configuration of the aluminum electrolytic capacitor, a cylindrical support portion 3a fitted into a cavity portion 1a, formed through the center of a capacitor element 1 is integrally provided with the inner bottom surface of a metal case 3. Thereby, the heat of the element 1 is radiated by diffusing its increased temperature instantaneously to the whole of the metal case 3, and the vibration resistance of the element 1 can be improved too so as to make realizable inexpensively the aluminum electrolytic capacitor, having suppressed temperature rise and high radiating efficiency.
