Beschreibung
Zusammenfassung:	The present invention is directed to a polyester resin composition for providing a reflector having excellent mechanical strength and heat resistance, maintaining high reflectance even in a heated environment such as an LED manufacturing process or a reflow soldering process, and having small change in shrinkage rate. The polyester resin composition for a reflective material is a composition comprising 30 to 80% by mass of a polyester resin (A) with a melting point or a glass transition temperature of 250°C or more, 10 to 35% by mass of a glass fiber (B) with a minor axis of 3 to 8 µm, 5 to 50% by mass of a white pigment (C), and 0.3 to 1.5% by mass of an olefin polymer (D) containing 0.2 to 1.8% of a functional group structural unit (all based on a total of (A), (B), (C) and (D) which is 100% by mass).
