Abstract

Disclosed is a method of manufacturing a rotation electric machine rotor, the method including a step of preparing a rotor core (32) having an annular shape when viewed in an axial direction and having a magnet hole (321, 322) in the axial direction and a first through hole (324) in the axial direction, an injection step of injecting a first molten material brought into a molten state by heating into the first through hole (324), and a magnet disposing step of disposing a permanent magnet (61, 62) in the magnet hole (321, 322) by injecting a second molten material brought into a molten state by heating into the magnet hole (321, 322) after the injection step, wherein the magnet disposing step includes fixing a magnet for the permanent magnet (61, 62) inserted into the magnet hole (321, 322) in the magnet hole (321, 322) as the second molten material is cured, or forming a bonded magnet for the permanent magnet (61, 62) in the magnet hole (321, 322) as the second molten material containing a magnet powder is cured.
