Abstract: A rotating electric machine 100 having a rotor 1, a stator 2, and a coil 3 including a coil conductor 31 wound around teeth 21b provided on at least one of the rotor 1 and the stator 2 includes a spacer section 42 configured to extend along a slot S formed between the teeth 21b and to be inserted between turns of the coil conductor 31 to define a gap G between the turns, and a cooling medium supply section 6 configured to distribute a cooling medium in the gap G. A notched section 421 cut out in such a manner that a widthwise dimension of the spacer section 42 is relatively short is provided in a middle of an extension of the spacer section 42.
