A cogging torque in a rotary electric machine is sufficiently reduced. The rotor core includes a magnetic pole having the base formed on the outer peripheral side of the storage space. A plurality of magnetic poles are provided in the circumferential direction, and include the first protrusion protruding from the base in one circumferential direction along the outer periphery of the rotor core, and the second protrusion which is provided on the opposite side to with the base interposed and protrudes from the base along the outer periphery of the rotor core in the other circumferential direction. At least one of the first protrusion and the second protrusion is located on the outer peripheral side from the first line segment which is a virtual line connecting the end of the first protrusion and the end of the second protrusion, and is provided such that the space is provided with respect to the first line segment.
