PROBLEM TO BE SOLVED: To realize an effective mass production with a simple automatic assembling machine securely peeling off an adhesive side of a laminated sheet at an accurate position, without using even partly resin film with low softening point, whenever and environment of a battery in use is in an abnormal state. SOLUTION: The manufacturing method of the battery comprises a molding process of providing a recessed groove 10 communicating with a storage room of a power generating element on the adhesive surface 4 of a first laminated sheet 1A, a first adhering process for heat adhering the adhesive surface 4 of the first laminated sheet and a second laminated sheet 1B without adhering the recessed groove 10 on the adhesive surface 4 of the second laminated sheet 1B, and a sealing process for heat adhering the inner face of the recessed groove 10 on the adhesive surface 4 of the second laminated sheet 1B. Further, the inner face of the recessed groove 10 of the first laminated sheet 1A is adhered to the adhesive surface 4 of the second laminated sheet 1B at an adhesive strength smaller than to the adhesive face other than that of the recessed groove 10, in the manufacturing method of the battery. |
