PROBLEM TO BE SOLVED: To provide a sealed battery capable of reducing a lead portion containing space, and reducing the resistance loss of a lead portion. SOLUTION: A lead portion 7 to be welded to the side end face 610 of an intermediate collector 61 is formed into wire-like. Thereby, the reduction of a lead portion containing space 9 and the resistance loss of the lead portion 7 can be realized. If the lead portion is formed by providing a large number of cut lines with a predetermined pitch in a length direction at no active material-coated side end portion of a collector, the same effect is caused. |
