description The invention discloses a zinc battery. A battery (1) is provided with an outer can (2), an electrode group (4) accommodated in the outer can (2) together with an alkaline electrolyte, and a sealing body (14) for sealing the outer can (2), and the electrode group (4) is formed by superposing and winding a positive electrode (6) and a negative electrode (8) with a separator (10) therebetween and is cylindrical as a whole. A negative electrode protruding end edge portion (12), in which a part of the negative electrode (8) partially protrudes, is positioned on the lower end surface portion of the electrode group (4), and the negative electrode protruding end edge portion (12) is in direct contact with the inner surface of the bottom wall (90) of the outer can (2). 本发明公开了一种锌电池。电池(1)具备外装罐(2)、与碱性电解液一起收容在外装罐(2)内的电极组(4)、以及对外装罐(2)进行封口的封口体(14)，电极组(4)是正极(6)和负极(8)隔着隔片(10)叠加并卷绕成螺旋状而形成的，作为整体形成圆柱状，负极(8)的一部分局部地突出的负极突出端缘部(12)被定位于电极组(4)的下端面部，负极突出端缘部(12)与外装罐(2)的底壁(90)的内表面直接接触。
