Abstract
This invention provides a battery can allowing for a reduced amount of gas forming therein, thus realizing lower production cost. The cathode canof an alkaline battery is cylindrically shaped and closed-bottomed, comprising an opening, a bodyand a bottom, with the bodybeing divided into an opening sealing sectionand an electrode mixture container sectionwhich are arranged in order from the opening, with the plate thickness tset for the electrode mixture container section, which is not less than 80% of the plate thickness tof the opening sealing section, with the plate thickness tof the electrode mixture container sectiongradually reducing in the region starting at the topmost point of the electrode mixture container sectionand ending at the set plate thickness t
