Abstract: A rotating electric machine includes a rotor, and a stator that has a stator core and a stator winding. The stator core has a plurality of slots. The stator winding is wound around the stator core as a plurality of electrical conductors is aligned in the radial direction in the slots. The stator has an insulating sheet member that is bent in a rectangular cylindrical shape, and is intervened between the electrical conductor and an inner wall surface of the slot. A length of a bend line formed extending in the axial direction on the insulating sheet member from a reference position in a central section of the insulating sheet member in the axial direction to a tip in the axial direction is configured shorter than a length from the reference position to an end in the axial direction of the sheet member.
