Summary:To make it possible to suppress a height of a coil end while ensuring insulation.SOLUTION: A segment conductor for a coil is so configured that the segment conductor is inserted into a stator core slot in which a plurality of slots are formed and each of the slots is connected to form stator winding. The segment conductor includes: a set of parallel linear portions inserted into the slots; a set of bend portions provided at ends of each of the linear portions; a head portion disposed between the set of linear portions; and a set of inclined portions connecting the head portion and each of the bend portions. A cross-section of a portion where a cross-section is continuous from the head portion has an aspect ratio smaller than that of a cross-section of a portion where a cross-section is continuous from the linear portion.SELECTED DRAWING: Figure 7 【課題】絶縁性を確保しつつ、コイルエンドの高さを抑えることができる。【解決手段】セグメント導体は、複数のスロットが形成された固定子鉄心のスロットに挿入され、それぞれを接続して固定子の巻線を構成する、コイル用のセグメント導体であって、スロットに挿入される直線状の平行な１組の直線部と、それぞれの直線部の端部に設けられる１組の屈曲部と、１組の直線部の間に配される頭部と、頭部とそれぞれの屈曲部とを接続する１組の傾斜部とを備え、頭部から断面が連続する部位の断面は、直線部から断面が連続する部位の断面に比べてアスペクト比が小さい。【選択図】図７
