The invention relates to a rotor manufacturing method. The rotor manufacturing method includes: a jig mounting step (S3) of mounting a holding jig to a rotor core, the holding jig holding the rotor core by sandwiching and pressing in a lamination direction of laminated steel plates; a rotor hub insertion step (S9) in which the rotor hub is inserted into the inner circumferential surface of the rotor core in a state where the rotor core and the holding jig are heated so that the rotor core is at or above an insertable temperature at which the rotor hub can be inserted into the inner circumferential surface of the rotor core; and a cooling step (S10) for cooling the rotor core and fixing the rotor core and the rotor hub, and the rotor hub insertion step (S9) is performed while maintaining the holding jig attached to the rotor core. 本发明涉及转子制造方法。在转子制造方法中，具备：夹具安装工序(S3)，将通过沿层叠钢板的层叠方向夹持并按压来保持转子铁芯的保持夹具安装于转子铁芯；转子毂插入工序(S9)，在以转子铁芯成为能够将转子毂插入转子铁芯的内周面的可插入温度以上的方式，对转子铁芯以及保持夹具进行了加热的状态下，将转子毂插入转子铁芯的内周面；以及冷却工序(S10)，将转子铁芯冷却，并固定转子
