PURPOSE:To obtain a flat type battery having high performance and high reliability by forming an insulating seal with a hot melt adhesive resin layer having low melting point bonded to a hot melt adhesive resin layer having high melting point bonded to each of positive and negative terminal plates. CONSTITUTION:A resin layer 22a (melting point 130 deg.C) and a resin layer 22b (melting point 100 deg.C) are stacked in order on the periphery of a positive terminal plate 21 and melt-bonded by heating from the terminal plate 21 side at 135 deg.C. A resin layer 24a and a resin layer 24b are melt-bonded to a negative terminal plate in the same way. A power generating element 28 comprising a positive mix 25, a separator 26, and a negative electrode 27 is arranged in the central part of the terminal plate 21, then the terminal plate 23 is arranged so that the resin layer 24b comes in contact with the resin layer 22b. The frame 32 of a fixture 31 kept at 105 deg.C is pressed against the part, corresponding to the resin layer 24a, of the terminal plate 23 to form an insulating seal 29 between the terminal plates 21, 23. |
