Abstract: In a method for manufacturing a rotor, each magnetic steel sheet has protrusions on its one surface and has recesses on the other surface at positions corresponding to the protrusions. The plurality of magnetic steel sheets are joined together as the protrusions of each magnetic steel sheet are fitted in the recesses of its adjoining magnetic steel sheet. A shaft member is inserted into a rotor core in the same direction as that in which the protrusions protrude.
