To provide a molding method of a multilayer foamed molded article, which is reduced in constriction on a layer structure and a shape of the multilayer foamed molded article to be molded, can be applied to the manufacturing of a variety of products, and is high in versatility.

In a molding method of a multilayer foamed molded article which fills two or more kinds of foaming raw materials into a cavity by dividing regions and integrates the raw materials by heating and foaming them, the first region 21 is defined and formed in the cavity by making it progress into the cavity with a portion of a metal mold for forming the cavity as a multilayer movable part 11, the multilayer movable part 11 is made to retreat by a prescribed amount after the first foaming raw material 31 is filled into the first region 21, and the second foaming raw material 32 different from the first foaming raw material 31 is filled into the second region 22 of the cavity formed by the retreat of the multilayer movable part 11 from a filling port 8a formed at the multilayer movable part 11.
