ABSTRACT:
A stack type electric double layer capacitor includes a plurality of unit cells, each with a pair of polarizing electrodes facing each other across a porous separator, a pair of current collecting members, and a gasket surrounding the electrodes and current collecting members. The gasket has a heat radiation notch in the direction parallel to or perpendicular to the stacking direction. This prevents heat from accumulating in the capacitor at the time of rapid charge and discharge, and thereby enhances the reliability of the capacitor.
