Provided is a resin molded body which has excellent flame retardance, weather resistance, shock resistance and tracking resistance. The resin molded body is composed of a thermoplastic resin composition comprising a thermoplastic resin, a polycarbonate, an elastomer, and a flame retardant. By adopting this combination of components, a Charpy impact value at 23°C measured in conformity with ISO 179/1eA is 15 kJ/m2 or more and flame retardance measured under a condition of thickness of 1.0 mm and in conformity with UL94 is V-0 or more, and a resin molded body which can be used favorably outdoors is produced.
