Rotating electric machine and cooling system for the rotating electric machine

A rotating electric machine comprising:

• a rotor;
• and
• a stator having a stator coil end, the stator coil end allowing flow of a cooling oil on a surface thereof during operation, wherein
• the stator coil end is a resin mold coil end including a coil end body formed of axial end portions of coils which constitute the stator and resin which embeds the coil end body,
• the resin mold coil end includes a plurality of column-shaped projections provided on the surface thereof, and
• the plurality of projections project along the radial direction or in a direction inclined with respect to the radial direction from locations distanced in the axial direction of an outer peripheral surface of the resin mold coil end at a plurality of positions along the circumferential direction.
