Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyester composition which comprises a thermoplastic polyester using an antimony compound as a catalyst, and a partially aromatic polyamide, prevents an increase in darkness, and is excellent in transparency, flavor retainability, and thermal stability, or in transparency, flavor retainability, thermal stability and gas barrier property, and to provide a polyester molded article comprising the same. SOLUTION: The polyester composition comprising 99.9 wt.% of a polyester containing an antimony compound, and 0.1 to 30 wt.% of a partial aromatic polyamide is characterized in that the content (P1) of phosphorus atom in the partial aromatic polyamide and the content (A) of the partial aromatic polyamide satisfies the following expression (1) : 0
