Abstract
A rotary electric machine includes a rotor that rotates integrally with a rotary shaft and a stator disposed outside the rotor in a radial direction. In the stator, a coil is wound on a stator core, and a coil end of the coil exposed to an outside from an end portion of the stator core is cooled by a liquid coolant. The rotary electric machine further includes a coil end cover formed of an insulating material and configured to cover at least an outer circumference of an upper region of the coil end. A liquid coolant passage through which a liquid coolant flows toward a coil end is provided in the coil end cover.
