Claims

[Scope of claim for utility model registration] A cylindrical metal battery case with a bottom that also serves as a terminal, a power generation element housed within this case, and a seal that fits into and closes the inner periphery of the open end of the case. The case has a gasket and a dish-shaped metal terminal plate assembled on the sealing gasket and connected to the power generation element by a current collector, and the open end of the case is curled inward. Therefore, in a dry cell having a structure in which the outer peripheral cylindrical portion of the sealing gasket is compressed between the case and the outermost peripheral portion of the terminal plate, and an outer film is attached around the case; A terrace section that is parallel to the central plane section is formed in the middle of the sloped section from the outermost part to the outermost peripheral section, and the heights of the upper end of the case and the terrace section are made almost the same by the curling process. In addition, a dry battery characterized in that the upper edge portion of the exterior film is also configured to cover the terrace portion.
