In an assembly battery (100) to be used as the power source of an automobile, a cathode collector plate (21) and an anode collector plate (23) are arranged at every two ones adjoining in a stacking direction of a plurality of bipolar secondary batteries. The cathode collector plate (21) (and the anode collector plate (23)) is caused to function as a radiation member, too, by the flow of a cooling medium therein. No cooling tab need be connected with the anode collector plate (23) (or the cathode collector plate (21)) for cooling the assembly battery (100). In the assembly battery (100), therefore, no portion bulges out from the anode collector plate (23) (or the cathode collector plate (21)). As a result, the assembly battery (100) can be cooled in its inside while being reduced in size. |
