PROBLEM TO BE SOLVED: To provide a polyester resin composition which has excellent flavor retentivity and does not cause transparency deterioration due to the staining of a mold and from which hollow molded articles having excellent heat-resistant dimensional stability and the like can efficiently be produced. SOLUTION: This polyester resin composition containing a polyester resin (1) consisting mainly of an aromatic dicarboxylic acid component and a glycol component and containing a phosphorous compound in a phosphorus atom content of 100 to 5,000 ppm and a polyester resin (2) consisting mainly of an aromatic dicarboxylic acid component and a glycol component, as main components is characterized in that the polyester resin (1) has a free aromatic dicarboxylic acid content of≤10 ppm, a free glycol content of≤1,500 ppm, a free aromatic dicarboxylic monoglycol ester content of≤50 ppm, and a free aromatic dicarboxylic acid diglycol ester content of≤100 ppm, and the polyester resin (2) contains a compound containing at least a kind of element selected from the group consisting of Al, Ti, Mn, Fe, Co, Zn, Nb, Mo, Cd, In, Sn, Ta, and Pb.
