とを特徴とする偏平型密閉式電池。It is constructed by fitting a first dish-shaped metal can and a second dish-shaped metal can with a smaller outer diameter facing each other, and inserting an annular sealing gasket between the peripheral edges of both metal cans. In a flat sealed battery in which a power generation element formed by stacking an anode mixture, a separator, and a cathode mixture is sealed in a flat case, the peripheral subdivision of the second dish-shaped metal can has a corresponding A double-folded flange is formed that extends outward from the outer diameter of the bottom of the can and is substantially parallel to the bottom, and the sealing gasket is attached so as to touch and enclose both the upper and lower surfaces of this flange, A flat sealed type characterized in that the opening end of the peripheral edge of the second dish-shaped metal can is bent inward so as to be substantially parallel to the flange, thereby compressing the sealing gasket. battery.
