PROBLEM TO BE SOLVED: To provide a rotary electric machine improving a torque characteristic by relieving magnetic saturation in a yoke without enlarging the size of the rotary electric machine. SOLUTION: A stator includes a cylindrical yoke 1, a plurality of arc-like permanent magnets 2 in which notches 12 abutting on the cylindrical yoke 1 at a center in a circumferential direction and separating the cylindrical yoke 1 in an end in the circumferential direction are formed and which are arranged on an inner peripheral face of the cylindrical yoke 1 by leaving a gap in the circumferential direction, and an auxiliary yoke 5 arranged between the cylindrical yoke 1 and the notch 12 to connect the confronted notches 12 of the adjacent permanent magnets 2.
