To provide a manufacturing method for a busbar further improved and new.SOLUTION: A manufacturing method for a busbar including a plurality of plate-like members and a linear welded part formed by welding two members included in the plurality of members includes, for example, while keeping an end part of one of the two members in a direction intersecting a thickness direction of the one member and the other member of the two members adjacent to each other, emitting laser beams including a plurality of beams, thereby forming a linear welded part between the end part of the one member in the direction intersecting the thickness direction and the other member, and along the end part. In this case, the welded part may be formed while the end part of the one member in the direction intersecting the thickness direction and an end part of the other member in the thickness direction are kept adjacent to each other. The welded part may be formed while the end part of the one member in the direction intersecting the thickness direction and the end part of the other member in a direction intersecting the thickness direction are kept adjacent to each other. In addition, the welded part may be formed while the one member and the other member overlap each other in their thickness directions.SELECTED DRAWING: Figure 2 【課題】より改善された新規なバスバーの製造方法を提供する。【解決手段】板状の複数の部材と、当該複数の部材に含まれる二つの部材を溶接した線状の溶接部と、を有したバスバーの製造方法は、例えば、二つの部材のうち一の部材の厚さ方向と交差した方向の端部と、二つの部材のうちの他の部材と、が隣接した状態で、複数のビームを含むレーザ光の照射によって、当該一の部材の厚さ方向と交差した方向の端部と当該他の部材との間に当該端部に沿う線状の溶接部を形成する。この場合、一の部材の厚さ方向と交差した方向の端部と、他の部材の厚さ方向の端部とが隣接した状態で、溶接部を形成してもよい。一の部材の厚さ方向と交差した方向の端部と、他の部材の厚さ方向と交差した方向の端部とが隣接した状態で、溶接部を形成してもよい。また、一の部材と他の部材とが互いの厚さ方向に重ねられた状態で、溶接部を形成してもよい。【選択図】図２
