PROBLEM TO BE SOLVED: To provide a polyester resin composition which is excellent in suitability to direct metal vapor deposition, surface smoothness, shock resistance and mold releasability and producing a molded article excellent in fogging property, and a light reflector excellent in brightness, in which a metal vapor-deposited film is formed on a molded article of the polyester resin composition. SOLUTION: The polyester resin composition comprises a polybutylene terephthalate resin (A), a polyethylene terephthalate resin (B), a spherical inorganic filler (C) having an average particle diameter of≤1.5μm, and a fatty acid metal salt (D) which ensures a weight reduction of≤1.50% when heat-treated in a nitrogen atmosphere at 200°C for 30 min after heat treatment in a nitrogen atmosphere at 100°C for 30 min.
