The polyester resin composition of the present invention is characterized by comprising: (A) 100 parts by weight of a high heat resistant polyester resin having a main chain formed by a structure derived from aromatic dicarboxylic acid and alicyclic diol, wherein the melting point of the high heat resistant polyester resin is 200° C. or more; (B) 0.1 to 80 parts by weight of white pigment; and (C) 1 to 40 parts by weight of polyolefin copolymer. The resin composition of the present invention further comprises 1 to 40 parts by weight of a high stiffness polyester resin having a main chain comprising a structure derived from aromatic dicarboxylic acid and aliphathic diol. The molding foam, which is obtained from the polyester resin composition and the manufactured polyester resin composition, has good flexibility, heat resistance, and yellowing resistance and can be used for an LED reflecting plate due to having improved impact strength.
