PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnet rotor with excellent jointing capability between a yoke and a magnet, a motor mounted with the magnet rotor, and the yoke used for the magnet motor. SOLUTION: This magnet rotor comprises the cylindrical yoke 11 and the cylindrical magnet 12 jointed so as to cover an outer-peripheral wall of the yoke 11, and grooves for applying adhesives to both the outer-peripheral wall of the yoke 11 and an inner-peripheral wall of the magnet for applying adhesives to the clearance and grooves between the outer peripheral wall of the yoke 11 and the inner-peripheral wall of the magnet 12 for jointing both of them. This magnet rotor is mounted on the motor. In manufacturing the yoke 11, grooving for forming the grooves is performed several times during a cylinder drawing process of the metallic plate.
