To provide a stator coil in which weld portions are in close contact and that has gaps in the other parts.SOLUTION: A stator of a rotary electric machine includes a plurality of segment coils including adjacent first and second coils, and a core portion having a space in which the segment coil is arranged, and each of the segment coils has a coated portion covered with an insulator and an exposed portion in which a conductor is exposed, and the exposed portion is formed with a protruding portion protruding from the side surface of the coated portion. The protruding portion of the first coil and the protruding portion of the second coil are in surface contact with each other, and the coated portion of the first coil is arranged with a gap between the coated portion of the first coil and the coated portion of the second coil.SELECTED DRAWING: Figure 6 【課題】溶接部は密着して、他の部分には隙間が空く固定子コイルを提供する。【解決手段】回転電機の固定子であって、隣接して配置される第１コイルと第２コイルとを含む複数のセグメントコイルと、前記セグメントコイルが配置される空間を有するコア部とを備え、前記各セグメントコイルは、絶縁体に覆われた被覆部と、導体が露出した露出部とを有し、前記露出部には、前記被覆部の側面より突出した突出部が形成されており、前記第１コイルの突出部と前記第２コイルの突出部とは、互いに面接触しており、前記第１コイルの被覆部は、前記第２コイルの被覆部との間に隙間を有して配置される。【選択図】図６
