PROBLEM TO BE SOLVED: To provide a method for manufacturing a foam molded article capable of easily controlling cell morphology. SOLUTION: In the method for manufacturing the foam molded article, after a foam resin composition is injected to fill a cavity by an injection machine, a movable mold of a mold is core backed to foam in the mold. The size of a foam cell of the obtained foam molded article is controlled by adjusting the detention time of the foam resin composition in a cylinder which is measured from the completion of resin measuring of the injection machine to the start of injection.
