The present invention prevents internal cracks occurring when an impeller molded using a fiber reinforced resin is manufactured by injection molding. This method for manufacturing an impeller is provided with: an injection step of filling a cavity with a molten resin containing reinforced fibers, from a gate side into which the molten resin flows, toward an opposite-gate side opposite to the gate side; and a dwell step of applying required pressure to the filled molten resin.
