PURPOSE:To establish a method and structure for welding a plate-shaped conductor which can certainly weld a plurality of such conductors, for example, bus bar, terminal plate, etc. CONSTITUTION:A plurality of plate-shaped conductors 1, 2 are piled one over another, and a cut-rise part 6 is formed upright using press dies 4, 5 in the overlapping part, and the formost 6a of this part 6 is irradiated with a laser beam 7. In the overlapping part of the plate-shaped conductors 1, a cut-rise part 6 is formed consisting of a plurality of rising pieces 61, 62 which are in tight attachment, and these pieces 61, 62 are welded together by laser irradiation. At the base board part of a terminal, a fold-back plate is provided in continuity confrontingly, and plate-shaped conductors are arranged between the base board part and fold-back plate, and a cut-rise part 6 is formed in the overlapping part 3 of the base board part, fold-back plate, and plate-shaped conductors. |
