PROBLEM TO BE SOLVED: To improve the cooling performance of passage conductor parts at a central part in a diametrical direction where the passage conductor parts are adjacent at both sides in a diametrical direction by laminating the passage conductor parts with an interval in a specific diametrical direction and forming a coil end. SOLUTION: A coil 2 is inserted into the slot of a stator core 1, and the starting end of a coil conductor is short-circuited before inserting into the slot. In a coil end 2d, passage conductor parts 22 are laminated in a diametrical direction while sandwiching a gap in the diametrical direction. The connecting conductor parts 22 projects in the direction reverse to a core toward a tip part 22a in an axial direction from an area near the core 1. The connecting conductor parts 22 are extended in a posture being inclined toward the outside from an area near the core 1 excluding the connecting conductor parts, and the ratio of the inclination of the connecting conductor parts 22 is larger at the connecting conductor parts 22, thus improving the cooling performance of the conductor parts 22.
