PROBLEM TO BE SOLVED: To provide a polyester resin composition excellent in direct metal vapor deposition and good in surface appearance, giving such a light-reflective molded product with part or the whole of its surface having metallized film as to have highly specular property and highly glittering feeling and cause no decline in glittering feeling due to clouding after exposed to high temperature. SOLUTION: The polyester resin composition for light-reflective product comprises 30-80 wt.% of a polybutylene terephthalate resin(A), 10-40 wt.% of a polyethylene terephthalate resin(B) and 0.1-40 wt.% of an inorganic filler comprising calcined kaolin(C)≤1.2μm in average particle size and a nonfibrous inorganic filler(D). This polyester resin composition also contains 0.01-1.0 pt.wt., based on a total of 100 pts.wt. of the components(A) to (D), of a releasant(E) less than 5 wt.% in weight reduction percentage when left to stand at 270°C for 10 min in a nitrogen atmosphere.
