METHOD FOR MANUFACTURING LAMINATED BUS BAR, MANUFACTURING APPARATUS FOR LAMINATED BUS BAR, LAMINATED BUS BAR

A method for manufacturing a laminated bus bar includes a first base member forming process of forming a plurality of first through-holes in a conductive flat plate-shaped first base member, a second base member forming process of forming a conductive flat plate-shaped second base member, a laminating process of forming a laminated body configured by laminating and fixing flat surfaces of the first base member and the second base member on and to each other, and a punching process of forming, in the second base member of the laminated body, second through-holes forming pairs with the first through-holes, the second through-holes being smaller than the first through-holes in portions overlapping with the first through-holes in a lamination direction of the first base member and the second base member.
