PROBLEM TO BE SOLVED: To provide a method in which a stable welding is possible, and further the time needed for sealing of a sheath body is shortened in the welding of an adhesive film to a lead wire in the battery packaging. SOLUTION: In the battery packaging wherein a sealant layer of a laminated body to constitute the sheath body of the battery does not show heat sealability to the lead wire, the closed sealing of the sheath body is carried out by interposing the adhesive film between the lead wire and the sealant layer to form a battery, and after heating the lead wire before connection and the adhesive film is pressurized and welded to the inner electrode, they are loaded to the inner electrode to make the battery body, and this is inserted into the sheath body and the closed sealing is carried out to form the battery.
