摘要： A battery having a collecting structure that can reduce internal resistance of the battery and a structure that allows easy manufacturing of the battery by the following processes is provided. An enlarged portion is formed near an opening end of a battery case and a supporting ledge is provided on the inner surface of the lower end of the enlarged portion. A collector of one polarity is bonded to an electrode plate group. A connection lead is bonded to the collector at one end and is bonded to a lower surface of a sealing member at the other end. An insulation gasket is mounted to a peripheral edge portion of the sealing member from a side opposite to the collector. The peripheral edge portion of the sealing member is supported by the supporting ledge with the insulation gasket interposed therebetween. Then, the peripheral edge portion of the sealing member is horizontally fastened and securely held via the insulation gasket by caulking the opening end of the battery case and performing a process for reducing the diameter of the enlarged portion.
