A method of manufacturing a rotor includes mounting a plurality of core members to a shaft in a state by inserting the shaft into a shaft hole that penetrates through the plurality of core members in a height direction. An inner diameter of the shaft hole is larger than an outer diameter of the shaft. The method includes pressing the plurality of stacked core members together in the height direction to form a stack in which the plurality of core members are located adjacent to each other, and the shaft hole is engaged with the shaft.
