The development department is developing an ultra-thin 5 mm flat battery. That is, 1 in the figure is a positive electrode terminal plate that supports a positive electrode mixture sheet 2. 3 in the figure is a negative electrode terminal plate carrying a negative electrode sheet 4 made of lithium or the like. These terminal plates 1.3 are separated between the positive electrode mixture sheet 2 and the negative electrode sheet 4.
The terminal plates 1.3 are stacked one on top of the other with a layer 5 interposed therebetween, and a frame-shaped insulating sealing body 6 made of heat-fusible resin is interposed between the opposing peripheral edges of each terminal plate 1.3. Then, each terminal plate 1.3 and the insulating sealing body 6 are heated and pressurized to fuse them together, thereby forming a positive electrode mixture sheet 2.3 as a power generation element. The negative electrode sheet 4 and separator 5 are sealed.
