Provided are polyester resin pellets obtained by melt-kneading terephthalic acid, ethylene glycol, either cyclohexanedimethanol or a bisphenol A ethylene oxide adduct, and a polyvalent ester to conduct polycondensation and thereafter subjecting the resultant polymer to solid-state polymerization, wherein the polyvalent ester is an ester of a carboxylic acid with a trihydric or higher polyol, the carboxylic acid having a hindered phenol group, the polyester resin has a content of units derived from the polyvalent ester of 0.005-0.04 mass%, and the polyester has an intrinsic viscosity of 0.9-1.5 dl/g. Such polyester resin pellets have excellent drawdown resistance, and molded articles obtained from the polyester resin pellets have satisfactory impact resistance and a satisfactory color tone. |
