    • An alkaline battery of the present invention includes a battery case, a power generating element housed in the interior of the battery case, and an assembled sealing part for closing the opening of the battery case. The assembled sealing part includes a resin sealing member. The sealing member includes a central cylindrical portion having a through-hole for inserting a shank of a negative electrode current collector therethrough, a peripheral cylindrical portion interposed between the periphery of the negative electrode terminal plate and the end portion of the opening of the battery case, and a joint portion for joining the central cylindrical portion and the peripheral cylindrical portion. The end portion of the opening of the battery case is curved such that the top of the peripheral cylindrical portion of the sealing member is wrapped therein, and the curved portion is crimped inward so that the periphery of the negative electrode terminal plate is fixed tightly. The sealing member includes polyamide having an equilibrium moisture content at a relative humidity of 50% of 0.9 to 1.7%.
    • 本发明的碱性电池包括电池壳体,容纳在电池壳体内部的发电元件和用于封闭电池壳体的开口的组装密封部件。 组装的密封部件包括树脂密封构件。 密封构件包括具有用于插入负极集电体的杆的通孔的中心圆筒部,插入在负极端子板的周边和电池壳体的开口的端部之间的周边圆筒部 ,以及用于接合中心圆筒部和圆周圆筒部的接合部。 电池壳体的开口的端部弯曲,使得密封构件的圆周圆筒部分的顶部被包裹,并且弯曲部分被向内卷曲,使得负极端子板的周边被紧固地固定。 密封构件包括在相对湿度为50%为0.9至1.7%的平衡水分含量的聚酰胺。
