PROBLEM TO BE SOLVED: To enhance volume efficiency, improve shock resistance and a heat radiation characteristic, and also extend a charge-discharge cycle life and improve productivity in manufacturing a battery by mounting a control circuit of a battery to a thermally-welded part of an armoring material to which deep- drawing is applied for forming a space for receiving a battery element. SOLUTION: A control circuit 5 is held on a thermally-welded part 2a of an armoring material and stabilized against vibration and shock. A space for mounting the control circuit 5 is effectively created by using the armoring material wherein a space capable of receiving a battery element is previously formed, for instance, by deep-drawing, so that the space can be utilized more effectively. Welded parts 2b, 2c are kept in a folded form by utilizing plastic deformation in themselves, for instance, the plastic deformation of metal foil constituting the armoring material without bonding them with an adhesive or the like. Thereby, a surface area is kept large, so that heat radiation capability can be improved and a cycle characteristic can also be improved. |
