PROBLEM TO BE SOLVED: To reduce the number of manufacturing processes to reduce a production cost, to prevent the leakage of a foamable resin to improve the appearance of a multilayered resin molded product and to form the multilayered resin molded product by combining various resin materials, in the multilayered resin molded product and its manufacturing method. SOLUTION: In the multilayered resin molded product, a connection layer which is composed of the same material as a skin layer and welded to a base material, is provided on the gap between a foamed layer and the base material, and the skin layer, the foamed layer, and the connection layer are formed by sandwich molding. Further, the manufacturing method for the multilayered resin molded product includes a process for forming the skin layer, the foamed layer and the connection layer by a sandwich molding method.
