That is, numerals 1 and 2 in the figure are positive and negative terminal plates, respectively. A frame-shaped insulating sealing body 3 made of, for example, polyethylene is interposed between these terminal plates 1.2. Further, in the space formed by the terminal plate 1.2 and the frame-shaped insulating sealing body 3, a positive electrode mixture sheet 4 made of a metal halide or oxide, a negative electrode sheet 5 made of a light metal such as lithium, A power generation element, which is interposed between the mixture sheet 4 and the negative electrode sheet 5 and includes a separator 6 impregnated with a non-aqueous electrolyte, is housed. Then, the power generation element is sealed by heat-sealing both the positive and negative terminal plates 1.2 and the insulating sealing body 3. According to a flat type battery having such a structure, the thickness can be reduced from 1.0 mm.
This can fully satisfy the above requirements.

For this reason, a flat type battery has been proposed in which one terminal plate, for example, the negative terminal plate 11, has a smaller area than the insulating sealing body 12, as shown in FIG. According to the battery having such a structure, since both the side surface of the negative electrode terminal plate 11 and the side surface of the positive electrode terminal plate 13 on the opposite side of the sealing body 12 are not exposed on the side surface of the insulating sealing body 12, as described above, the battery Even if a metal piece comes into contact with the side surface, short circuits can be prevented. However, in manufacturing this battery, a terminal plate (here, the negative terminal plate 11) having a smaller area than the sealing body 12 is aligned and bonded so that its entire side is spaced a predetermined distance from the side of the sealing body 12. It is difficult to do so. As a result, the negative electrode terminal plate 11 may be misaligned, resulting in poor appearance, or the negative electrode terminal plate 11 may be unevenly adhered to the sealing body 12, and the side surfaces of the positive and negative electrode terminal plates 11, 13 may be partially exposed on the side surfaces of the sealing body 12. If the metal piece comes into contact with the side surface of the battery, a short circuit may occur.
