description To provide a rotary electric machine which is improved in cooling performance. The rotary electric machine includes a rotor; and a stator which, being disposed opposite the rotor, has a stator core having a plurality of slots therein and a stator winding wound in the plurality of slots, wherein the stator has a plurality of coil ends which are formed protruding from an axial end face of the stator core and between adjacent ones of which is provided a radial clearance passing through from the inner diameter side to the outer diameter side, and wherein the stator includes a bus bar which, being disposed on the inner diameter side of the plurality of coil ends so as to occlude the clearances between the plurality of coil ends, guides a refrigerant, which is supplied from the radial direction of the stator, to the plurality of coil ends.
