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 (11) in a conductive flat plate-shaped first base member (10), a second base member forming process of forming a conductive flat plate-shaped second base member (20), a laminating process of forming a laminated body (1A) configured by laminating and fixing flat surfaces of the first base member (10) and the second base member (20) on and to each other, and a punching process of forming, in the second base member (20) of the laminated body (1A), second through-holes (21) forming pairs with the first through-holes (11), the second through-holes (21) being smaller than the first through-holes (11) in portions overlapping with the first through-holes (11) in a lamination direction of the first base member (10) and the second base member (20).
