PROBLEM TO BE SOLVED: To provide an injection molding method of a rubber molded product capable of smoothly injection-molding an unvulcanized rubber molded product by ensuring the flowability of the unvulcanized rubber composition injected in a mold and the demolding properties of the molded rubber molded product. SOLUTION: The mold 6 is heated to a temperature capable of ensuring the flowability of the unvulcanized rubber composition and, after the unvulcanized rubber composition is injected in the cavity 11 of the mold 6, the rubber molded product is cooled during a state that the rubber molded product molded in the cavity 11 is unvulcanized to eject the rubber molded product from the mold 6 in an unvulcanized state.
