Abstract

To provide a rotor manufacturing apparatus capable of reducing manufacturing cost for a rotor including a magnet fixed with a resin. A rotor manufacturing apparatus (1) includes: a first mold (3) including a resin receive space portion (31) receiving a resin to be supplied into an accommodation hole (212), and a flow path (32) through which the molten resin flows into the accommodation hole (212); and a second mold (4) configured to sandwich a rotor main body (21) in conjunction with the first mold (3). The first mold (3) includes: a first mold main body (34) including the resin receive space portion (31); a runner plate (35) having a flat plate shape and including a flow path main body (321) of the flow path (32), the runner plate (35) being detachable from the first mold main body (34); and a plurality of gate plates (36) each having a flat plate shape and each having a through-hole (361), the gate plates (36) being detachable from the first mold main body (34). A resin outlet (322) of the flow path (32) includes the through-holes (361) in the gate plates (36), the through-holes (361) communicating with one another in the state in which the gate plates (36) are stacked on top of one another in the thickness direction.
