Abstract
A rotating electric machine according to an embodiment of the present invention includes a rotor; a stator; an insulator; and a coil. The rotor rotates about a first axis. The stator includes teeth projecting toward the rotor. The insulator is attached to each of the teeth. The coil is wound around the insulator. The insulator includes a pair of side surface portions that are mounted on the teeth to generate a biasing force against the teeth in a twisting direction with respect to a direction of the first axis.
