PROBLEM TO BE SOLVED: To provide an electricity accumulation unit capable of more quickly cooling heat generated in a capacitor.SOLUTION: The electricity accumulation unit includes an electricity accumulating part 1 comprising the capacitor having a negative electrode terminal and a positive electrode terminal formed at both ends of an element and constituted of a collector exposed part which are joined with a terminal board 3 or an outer case 4, respectively, to make electrodes pulled out, and a pair of cooling plates 21a and 21b coming into contact with an external surface of the terminal board or an external bottom face of the outer case of the capacitor. Thus, since heat can be dissipated via a highly heat conductive material such as a metallic member from the electricity accumulating part 1 to the cooling plates 21a and 21b in the electricity accumulation unit, the heat of the capacitor during charging/discharging can be more efficiently cooled. |
