Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a polyester resin composition without deteriorating the transparency of a bottle body part with time even in a long-term continuous molding. SOLUTION: This polyester resin composition is obtained by compounding a polyester resin consisting essentially of ethylene terephthalate unit, having 0.70-0.90 dL/g intrinsic viscosity, further 1.0-3.0 mol.% ratio of diethylene glycol unit in the total diol units,
