PROBLEM TO BE SOLVED: To provide a rotary electric machine that improves insulating reliability by securing enough creepage distance between adjacently bonded parts. SOLUTION: A stator 2 of the rotary electric machine includes a stator core 32 and a stator winding fit to the stator core 32. This stator winding includes an inner conductor housed in a slot 35 of the stator core 32 and an outer conductor exposed in a shaft direction of a rotary shaft of a slot 35 rotor 3, and also includes the bonding part 33f of which a surface is composed of a plurality of conductors 33j covered with insulating films 33k and which is obtained by bonding the other conductor 33j to an exposing part formed at the end of the conductor 33j by removing the insulating film 33k by a predetermined length. In the stator 2 of such a configuration, the insulating film 33k which has a peeling insulating film part 33ka peeled off from the conductor 33j by the predetermined length in a boundary portion with the exposing part is provided, and this peeling insulating film part 33ka is obliquely separated from the conductor 33j so as to be widened toward the exposing part.
