This type is laminated as shown in Figures 2 and 3, and in the case of Figure 2, the circumference of the positive current collector plate of one single battery A is lengthened to create a battery. However, the other single battery B is created by making the negative electrode current collector plate longer. Thereafter, the two batteries are stacked and thermally bonded to the long portions of the positive current collector plate and the negative current collector plate via a metal adhesive resin. In addition, in the battery shown in Figure 2, the -tr halator D portion of the unit cell is made long, and the separators D are bonded together to form a stacked battery.
