Abstract: A stator for a rotational electrical machine includes a cylindrical stator core and a stator winding. The stator core includes slots arranged at intervals in a circumferential direction. The slots pass through the stator core in an axial direction. The stator winding is obtained by joining together ends of U-shaped conductors inserted through the slots. A second insertion part is located away from a first insertion part in the circumferential direction and is inserted in its corresponding slot. A joining end part is joined to another U-shaped conductor at a joining position away from the insertion part in the circumferential direction. The joining end part includes a first bent part and at least one second bent part. The first bent part is bent near an opening of its corresponding slot. The second bent part is bent between the first bent part and the joining position.
