PROBLEM TO BE SOLVED: To provide a polyester resin composition of which molded article is excellent in impact resistance and prevents the occurrence of pinholes that are caused by the bending and shaking at the time of the transportation and of the carry. SOLUTION: The resin composition of polyester resins, contains in a specified ratio, (a) a polyester resin which comprises a dicarboxylic acid unit comprising a terephthalic acid unit mainly and the diol unit consisting mainly of a cyclohexane dimethanol and an ethylene glycol unit with a mole ratio of 3:97 to 12:88 and which has a melting point of 210-250 deg.C and an intrinsic viscosity of 0.6-1.5 dl/g; (b) a polyester resin which comprises a dicarboxylic acid unit comprising a terephthalic acid unit mainly and the diol unit consisting mainly of a cyclohexane dimethanol unit and an ethylene glycol unit in a mole ratio of 60:40 to 95:5 and which has a melting point of 210-270 deg.C and an intrinsic viscosity of 0.6-1.5 dl/g; and (c) a polyester block copolymer.
