Abstract
A method of producing a rotating electric machine stator includes an insertion step, bending step, and pressing step. In the insertion step, two leg portions of each U-shaped coil wire of a stator coil are inserted into different slots, such that protruding portions as distal end portions of the leg portions protrude in parallel with an axial direction of the stator core. In the bending step, the protruding portion of a first leg portion is bent in a first circumferential direction of the stator core, at a proximal end portion of the protruding portion as a bending start point, from a condition where the protruding portion protrudes from the slot in parallel with the axial direction of the stator core. In the pressing step, a distal end of the protruding portion bent in the first circumferential direction is pressed toward its proximal end in a second circumferential direction.
