PROBLEM TO BE SOLVED: To provide a polybutylene terephthalate (PBT) excellent in color, resistance to hydrolysis, heat stability, transparency, and moldability, decreased in foreign matter, and capable of suitably used for a film, a monofilament, a fiber, an electrical and electronic part, an automotive part, etc., and to provide a composition of the same. SOLUTION: This PBT contains titanium of which the amount is not more than 80 ppm as titanium atom, and has a carboxy end group concentration of 6.0-17.0μeq/g and an intrinsic viscosity of 0.65-0.87 dL/g. The PBT composition resistant to the hydrolysis contains the PBT (A) in an amount of 100 pts.wt., an epoxy compound (B) in an amount of 0.01-20 pts.wt., and a reinforcing filler (C) in an amount of 0-200 pts.wt.
