摘要：
Heat discharging property of the stator coil end is improved effectively in a rotating electric machine. A motor as the rotating electric machine includes a stator and a rotor. The stator includes a stator core and resin mold coil ends provided on both axial ends thereof. Column-shaped projections projecting in the axial direction are provided on axial side surfaces of resin mold coil ends at a plurality of positions. Cooling oil supplied from above the resin mold coil ends effectively cools the resin mold coil ends.
