PROBLEM TO BE SOLVED: To reinforce a part which is in contact with a slot end corner part of insulating paper. SOLUTION: By using a notch dividing a single end of insulating paper into a central part and both side parts, both the side parts are folded back toward the direction opposite to a contact surface with a coil. Tip edges of the folded- back segments 6a of both the side parts are engaged with the end surface of a stator core 1. The central part is folded back toward the contact surface side with a coil, inside the folds in both the side parts. The tip of the folded- back segment 5a in the central part is inserted in a slot 2.
