The present invention provides an automotive rotary electric machine stator and a manufacturing method therefor that can increase electric conductor space factor inside slots, enabling electric power generating efficiency and output torque to be improved, and that can suppress the occurrence of damage to insulating coatings of root portions of coil end portions, enabling electrical insulation to be ensured. In the automotive rotary electric machine stator according to the present invention, a stator winding is constituted by distributed windings, slot-housed portions and root portions of coil end portions are formed so as to have flat cross sections, and the slot-housed portions are housed in the slots in contact with each other so as to line up in a single column in a radial direction such that long sides of the flat cross sections are oriented circumferentially. Flatnesses of root portions of the coil end portions that are radially adjacent and that extend outward in different circumferential directions from the slots are mutually different. |
