To provide a rotor manufacturing apparatus for manufacturing a rotor having an accommodation hole for accommodating a magnet, the rotor manufacturing apparatus being capable of easily positioning a rotor main body in supplying a resin into the accommodation hole. A rotor manufacturing apparatus (1) is a rotor manufacturing apparatus for manufacturing a rotor including a rotor main body (21) having a hole (211) located at its center and an accommodation hole (212) accommodating a magnet (22) and the magnet (22) accommodated in the accommodation hole (212) and fixed in the accommodation hole (212) with a resin. The rotor manufacturing apparatus (1) includes: a first mold (3) including a resin receive space portion (31) receiving the resin to be supplied into the accommodation hole (212), a flow path (32) through which the molten resin flows into the accommodation hole (212), and a contact portion (33) inserted in the hole (211), the contact portion (33) being in contact with an inner peripheral face of the hole (211); and a second mold (4) configured to sandwich the rotor main body (21) in conjunction with the first mold (3).
