摘要： Please substitute the new Abstract submitted herewith for the original Abstract: Provided is a rotary electric machine that achieves high motor efficiency with little loss. This rotary electric machine is equipped with: a stator core arranged opposing the circumferential surface of a rotor, and in which multiple slots, wherein openings opening toward the rotor are formed, are formed in the circumferential direction; and coils inserted into the slots. A mixture of a soft magnetic powder and a resin material is formed in the openings of the slots, and the relative permeability of the mixture is 5-35.
