    • An alkaline dry battery of the present invention has a cylindrical separator (4), and a bottom separator (9) including a first bottom paper (10) and a second bottom paper (11). The first bottom paper (10) has a first bottom part (10a) and a first rising part (10b) which is placed around the first bottom part (10a) and upright along the inside of the cylindrical separator (4). The second bottom paper (11) has a second bottom part (11a) and a second rising part (11b) which is placed around the second bottom part (11a) and upright along the outside of the cylindrical separator (4). The first rising part (10b) and the second rising part (11b) sandwich an end of the cylindrical separator (4) therebetween. With the use of the bottom separator (9), it is possible to fix the bottom-side end of the cylindrical separator (4), and therefore to provide a highly reliable alkaline dry battery with excellent discharge performance because the bottom separator (9) does not move even when a vibration or impact is applied to the alkaline dry battery.
    • 本发明的碱性干电池具有圆柱形隔膜(4)和包括第一底纸(10)和第二底纸(11)的底部隔板(9)。 第一底纸(10)具有第一底部部分(10a)和第一竖立部分(10b),该第一竖立部分(10b)围绕第一底部部分(10a)放置并且沿着圆柱形分离器(4)的内部竖立。 第二底纸(11)具有第二底部(11a)和第二上升部分(11b),该第二底部部分(11b)围绕第二底部部分(11a)放置并且沿着圆柱形分离器(4)的外侧立起。 第一上升部分(10b)和第二上升部分(11b)夹在其间的圆柱形分离器(4)的一端。 通过使用底部分离器(9),可以固定圆筒形分离器(4)的底侧端部,从而提供具有优异的排出性能的高可靠性碱性干电池,因为底部隔板(9) 即使对碱性干电池施加振动或冲击也不会移动。
