PROBLEM TO BE SOLVED: To develop a foamed thermoplastic resin molding which is light in weight, high in rigidity, and excellent in junction strength between a base material and a bracket. SOLUTION: In the foamed thermoplastic resin molding in which the bracket is formed on the base material to be integrated with the base material, at least the base material has a foamed layer, the densityρof the foamed layer of the base material is 0.7 g/cm3 or below, and the expansion ratio of the junction between the bracket and the base material is 1-1.3.
