ELECTRIC DOUBLE-LAYER CAPACITOR

The capacitor has capacitor cells (1) that are formed by storing a laminate of positive electrodes, negative electrodes, and separators in a bag-like soft case with an electrolyte. A heat conduction frame (15) clamps the heat radiation fins (5a) projecting in strips in peripheral rim of the soft case. A metallic heat radiation hard case (21) stores the capacitor cells in contact with the heat conductive frame.
