PROBLEM TO BE SOLVED: To reduce the weight of a foamed resin molded object while enhancing the cushioning properties thereof and to shorten a molding cycle, in the foamed resin molded object utilizing a two-color injection molding process and a method for molding the same. SOLUTION: In the foamed resin molded object 22 constituted by covering the outer surface of a core layer 23 with a skin layer 24, the core layer 23 is brought to a fine foamed structure and enhanced in flowability by mixing a supercritical fluid(SCF) of such as CO2 or N2 with a thermoplastic elastomer(TPE) to be enhanced in its cushioning capacity. Further, the cooling/ solidifying time of the skin layer 24 is shortened by the fine foamed structure of the core layer 23 and the surface hardness and abrasion properties of the skin layer 24 are enhanced.
