Abstract
A method for producing a battery comprises a deformation step for moving a first metal foil forming a pair of perpendicularly intersecting portions of a first metal, respectively, toward the outside in a second radial direction while enlarging the inside diameter, in the second radial direction, of a first metal winding part by making a force act on the pair of perpendicularly intersecting portions of a first metal toward the outside in the second radial direction, and a resistance welding step for pressing a pair of first metal welding portions toward the inside in a first radical direction under a state where the first terminal welding part of a first current collecting terminal member is arranged on the radial by inside of the first metal winding part after the first metal winding part is deformed.
