PROBLEM TO BE SOLVED: To provide a composite resin molding excellent in adhesion between a thermoplastic and a polystyrene resin. SOLUTION: The composite resin molding is composed of a substrate and a surface member formed of a thermoplastic resin (IV) on at least a surface part of the substrate, the substrate is formed by a resin composition (III) comprising 90-10 mass parts of a polystyrene resin (I) and 10-90 mass parts of a copolymer (II) of vinyl cyanide-aromatic vinyl compounds, and the content of the acetone soluble vinyl cyanide unit is 1-15 mass% in the copolymer (II) of vinyl cyanide-aromatic vinyl compounds.
