Abstract
A rotating electric machine including a rotor, a stator, and a case forming outflow holes through which a refrigerant flows out toward an extra-slot conductor of a stator coil. The outflow holes are arranged above the extra-slot conductor, and when the bending direction of the extra-slot conductor with respect to an intra-slot conductor arranged on the outermost diameter side in a slot in the stator coil on an upper portion of the stator is a coil bending direction, the first outflow hole is arranged on the bending direction side with respect to a vertical line passing through the rotation center axis, and the second outflow hole is arranged on a side opposite to the bending direction with respect to the vertical line, and the arrangement angle of the second outflow hole with reference to the vertical line is larger than the arrangement angle of the first outflow hole with reference to the vertical line.
