PROBLEM TO BE SOLVED: To make the hardness of a laminated resin molding in which a skin layer and resin foam are laminated different in accordance with a part. SOLUTION: A cavity 20 is formed by a lower mold 12, a first horizontal mold 14, a second horizontal mold 16, and an upper mold 18 which constitute a molding machine 10. An injection machine 22 is installed so that a raw material 28 flows in the extension direction of the cavity 20 in relation to the first horizontal mold 14, and an air blow pipe 30 is set in the second horizontal mold 16. When the raw material 28 is injected from the injection machine 22, a gas such as compressed air is introduced into the cavity 20 through the air blow pipe 30, and the raw material 28 is pushed to the side of the injection machine 22 by the gas. That is, in a part close to the second horizontal mold 16 in the raw material 28 (the resin foam 42), the flow is retarded, so that bubbles 40 grow greatly as compared with a part close to the first horizontal mold 14.
