The present invention provides a battery casing, a film packaging battery, and a method for manufacturing the same. The present invention relates to the battery casing which has a casing body comprising a stack film having a fusing layer and a metal film. Drawing molding is performed on the surrounding wall of the casing body to allow the fusing layer of the stack film to be convex to a receiving unit. A concave part is formed on the outer surface. Thereby, the fusing layer of both ends of a pair of facing concave walls which are erected by being folded from a square bottom, is fused to the fusing layer of both edges of a pair of facing walls which are erected by being folded from the bottom part. |
