Zusammenfassung:To provide a connection method for a square-shaped conductor capable of causing a sufficient current to flow in a connection of conductors.SOLUTION: A connection method for a square-shaped conductor includes the steps of: in the state where a first end face of a first conductor having a rectangular cross section and a second end face of a second conductor having a rectangular cross section are adjacent to each other, disposing a cover member over the first end face and the second end face so as to cover at least partially the first end face and the second end face; and melting the entire cover member by irradiating the cover member disposed over the first end face and the second end face with an energy beam, and generating a melting layer in which the cover member, an end portion of the first conductor and an end portion of the second conductor are molten.SELECTED DRAWING: Figure 5 【課題】導線同士の接続部において十分な電流を流すことができる角型導線の接続方法を提供する。【解決手段】一実施形態に係る角型導線の接続方法は、矩形断面を有する第1導線の第1端面と、矩形断面を有する第2導線の第2端面とが隣り合わせになった状態で、前記第1端面及び前記第2端面に跨って前記第1端面及び前記第2端面の少なくとも一部を覆うように覆い部材を配置するステップと、前記第1端面と前記第2端面とに跨って配置された前記覆い部材にエネルギービームを照射して、前記覆い部材の全体を溶融して前記覆い部材と前記第1導線の端部と前記第2導線の端部とが溶融した溶融層を生成するステップと、を備える。【選択図】図5
