To provide a polybutylene terephthalate resin composition having flexibility, ductility, and shock resistance and having a greatly improved hydrolysis resistance, weatherresistance, and compatibility, and a molded body (fuel tube, etc.) using the composition.
This composition contains (B) 10 to 80 pts.wt. acrylic core shell type elastomer, (C) 0.01 to 5 pts.wt. aromatic polycarbodiimide compound, and (D) 0.01 to 5 pts.wt. antioxidant in relation to 100 pts.wt. polybutylene terephthalate resin constituted by (A) a PBT homopolymer and/or a PBT copolymer, and a PBT elastomer. The resin composition and its molded body are provided, where the PBT resin (A) is made of (A1) PBT homopolymer and/or PBT copolymer, and (A2) polyester elastomer with a weight ratio of former/latter=30/70 to 70/30.
