Summary:The invention relates to a method for manufacturing a rotor. In a setting step, a plurality of steel plates configuring a rotor core stacked in an axial direction of a rotor is set in a predetermined position in a mold that is capable of being opened and closed by relative movement in the axial direction. In a casting step, molten metal is fed into a molten metal introduction passage to form a conductive member of the rotor. The molten metal introduction passage has a ring-shaped gate that is opened so as to oppose one axial end surface of the steel plates set in the mold. In a cutoff step, the molten metal is cut off in the molten metal introduction passage so as to be separated into a gate side and a molten metal introduction opening side. In a mold-releasing step, the mold is opened such that a casting configuring the rotor is removed from the mold.
