PROBLEM TO BE SOLVED: To provide a rotor for a hybrid stepping motor only by stamping a material to be worked using a die to form a core plate at a prescribed precision, with no polishing of a rotor part. SOLUTION: The manufacturing method in which a core plate 20 is provided with many small teeth 14 on the outer peripheral edge by stamping with a die, which comprises a hole through which a rotor shaft is penetrated as well. A prescribed number of core plates 20 are stacked for integration to form a rotor part. The rotor shaft is inserted in the rotor for assembly, is characterised in that the prescribed number of core plates 20 are stacked for integration to form the rotor part, and after the rotor shaft is inserted to the rotor part, the rotor part is built into a motor without polishing the outer peripheral surface of the rotor part.
