Claim:
1. A rotating electrical machine comprising: a rotor, and a stator that has a stator core and a stator winding; wherein, the stator core is disposed in a radial direction facing the rotor and has a plurality of slots extending in an axial direction, and arranged in a circumferential direction; the stator winding is wound around the stator core as a plurality of electrical conductors and is aligned in the radial direction in the slots; the stator has an insulating sheet member that is bent in a rectangular cylindrical shape to match a sectional shape of the slot, 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, the bend line is formed separately into a plurality of bend lines in the axial direction, the bend lines are spaced apart in the axial direction from each other, the insulating sheet member is folded only along the bend lines, and a portion wherein no bend line is formed is present between two of the bend lines formed separately in the axial direction.
