PROBLEM TO BE SOLVED: To provide a method for manufacturing a battery having a high welding strength of a current-collecting body and electrode groups using the current- collecting body having a small electric resistance. SOLUTION: A high resistance member containing a metal having a higher resistance value than an electric resistance of a current-collecting body 8 as a main component is disposed between electrode groups 10 and the current- collecting body 8 and the current-collecting body 8 is mounted to the electrode groups 10 by a resistance welding. The high resistance member is preferably an alloy containing two kinds or more of iron, nickel and chrome as main components and the current-collecting body 8 uses a material including a steel plate, a nickel-plating steel plate or a nickel as a main material, which makes it possible to efficiently weld without increasing an internal resistance of battery.
