PROBLEM TO BE SOLVED: To provide a polyester resin composition molding excellent in toughness (tensile strength, tensile elongation at break), and excellent in electric properties such as flame retardancy and tracking resistance.SOLUTION: A molding is composed of a polyester resin composition containing 100 pts.mass of a thermoplastic polyester resin (A), 3 to 60 pts.mass of a brominated polystyrene (B), 0.5 to 20 pts.mass of a polycarbonate resin (C), and 0.5 to 20 pts.mass of an antimony compound (D), wherein the content of free bromine in the resin composition is ≤500 ppm; the thermoplastic polyester resin (A) forms a continuous phase, and a brominated polystyrene (B) phase, a polycarbonate resin (C) phase and an antimony compound (D) phase are dispersed in the continuous phase; and the surface layer of the molding has a morphology in which the brominated polystyrene (B) phase is oriented in the flow direction of the resin. |
