LAMINATE PACK BATTERY

PROBLEM TO BE SOLVED: To reduce the short circuit failure of a lead terminal part which occurs in heat sealing and to realize a high productive efficiency by arranging an adhesive containing a material not fused at a temperature for thermal fusion on the periphery of the lead terminal, and connecting the adhesive to a thermally fusible resin. SOLUTION: In a laminated electrode group, lead terminals 3 are mounted on a part of the respective current collectors of a positive electrode and a negative electrode. An aluminum lamination sheet 5 is set with the mutually adhered surfaces of thermally fusible resins upside, and the electrode group is set thereon. An adhesive 4 is arranged in the part nipped by a thermally fusing part 6 of the lead terminals 3. The adhesive 4 is desirably arranged on both sides of each lead terminal. The adhesive 4 can be arranged so as to bridge the two lead terminals 3, or independently on the two lead terminals 3. Otherwise, the necessary part of the lead terminals 3 may be preliminarily thermally coated with the adhesive 4.
