PROBLEM TO BE SOLVED: To provide a urethane molding method, which brings no increase of a production cost, with no limitation on the opening position of a gate to a base material. SOLUTION: The urethane molding method, molds a urethane molding 10 having a foamed material 26 interposed between the skin of which and the base material by setting a base material 16 having a required shape in a core mold 12 and, at the same time, setting a skin 18 having the required shape in a cavity mold 14, casting a urethane from a urethane casting nozzle 22 on the core mold side the molds in a enclosed space 24 through a gate 20 provided in the base material after clamping and expanding and solidifying the urethane. The urethane is cast in the enclosed space 24 between the skin and the base material through a gate as another opening part of a runner 28 by holding the urethane casting nozzle 22 against one opening part 30 of the runner 28 formed on the rear surface of the base material in a required pattern so as to function as a flow passage of the urethane and casting the urethane from the nozzle.
