PROBLEM TO BE SOLVED: To easily and surely form a plurality of leads in a radial manner that are led out in circumference and in a row. SOLUTION: In a lead-forming process for bending a plurality of leaf like leads 11a, 12a led out in the axial direction of a cylindrical accumulated layer electrode body, for example a battery main body 2 in the radial direction, it is formed by inserting a forming shaft of which leading edge is conical into a center hole 2h of the cylindrical accumulated layer electrode body and inclining the leaf-like leads 11a, 12a in the radial direction that its section is a circular from the axial direction of a battery body. |
