The present invention relates to a polyester-based resin composition and a molded article manufactured using the same. More particularly, the present invention relates to a polyester-based resin composition including 93 to 99.5 % by weight of a polybutylene terephthalate resin; 0.1 to 3 % by weight of a polar group-containing lubricant; and 0.1 to 2 % by weight of an antioxidant and a molded article manufactured using the polyester-based resin composition.According to the present invention, a polyester-based resin composition having excellent fluidity, mechanical properties, thermal stability, injection stability, and surface properties and a molded article manufactured using the same may be provided. In particular, due to excellent surface properties thereof, the polyester-based resin composition does not exhibit iridescence caused by diffuse reflection. In addition, the polyester-based resin composition has a low haze value. Accordingly, the polyester-based resin composition may be used to manufacture a molded article such as an automotive headlamp bezel.
