PROBLEM TO BE SOLVED: To provide a polyester resin composition which has characteristics suitable for blow molding, is excellent in moldability during blow molding, and is capable of giving a blow-molded article having excellent impact resistance.SOLUTION: The polyester resin composition contains: a polyester resin (A) in which an acid component is mainly composed of terephthalic acid, a glycol component is mainly composed of ethylene glycol and 1,4-butanediol, and the mass ratio of the ethylene glycol to the 1,4-butanediol is 80/20-30/70 and which has a crystal melting point of 160-205°C and an intrinsic viscosity of 0.5-1.4; and a polyester block copolymer (B). The polyester block copolymer (B) is contained in an amount of 0.1-25 pts.mass based on 100 pts.mass of the polyester resin (A).SELECTED DRAWING: None |
