To provide a method of manufacturing a coil of a rotary electric machine that can prevent deterioration of insulating film due to the twisting of tip for coil end of a conductor segment by avoiding addition of complicated manufacturing process and controlling increase of manufacturing work and cost.
Since many pin-type jigs 300 are individually inserted adjacently almost in the diameter direction to the circumference direction of the base end tip S of each coil end projected from one end surface 201 of a stator core 200 and the base portion of the tip S for coil end using as the fulcrum the pin-type jig 300 having the round cross-section in the circumference direction is twisted in the circumference direction concentration of stress at the base end portion of the tip S for coil end can be alleviated with that in the existing method where the base end portion of the tip S for coil end is twisted using the cross-section at the right angle to the circumference portion of slot of the core 200 as the bending fulcrum.
