PROBLEM TO BE SOLVED: To ensure insulation between electric conductors in a coil end portion. SOLUTION: Gaps are formed between electric conductors 331a, 331b of a coil end 31b of a stator winding and other conductors 332a, 331b which are adjacent in the radial direction. Since the gaps are formed between the electric conductors adjacent in the radial direction, contact for the electric conductors which are adjacent in the radial direction, and damages to the insulating films of the electric conductors which is caused by the contact can be reduced when a vehicle vibrates. Thereby insulation between electric conductors can be ensured, so that short-circuiting due to mutual contacts of the damaged portions of the insulating films can be prevented.
