摘要： A stator (1) includes a cylindrical stator core (3) having a plurality of slots on an inner peripheral side, a first coil (5) having an annular shape and partially located in two first coil slots (41), and a second coil (6) having an annular shape and partially located in two second coil slots (42). The first coil (5) has two first coil end portions (52). The second coil (6) has two second coil end portions (62). The one second coil slot (42) is located on one side in the circumferential direction with respect to the first coil slot (41) located on one side in the circumferential direction of the two first coil slots (41). The other second coil slot (42) is located on the other side in the circumferential direction with respect to the first coil slot (41) located on the other side in the circumferential direction. The sum of the lengths of the two second coil end portions (62) is 1.3 times or more than 1.3 times the sum of the lengths of the two first coil end portions (52).
