Abstract: The present invention provides a polybutylene terephthalate resin composition, having performance of high durability and the like in a cold cycle environment, and having high strength. Specifically, relative to 100 parts by weight of a polybutylene terephthalate resin (A) having 30 meq/kg or less of the amount of terminal carboxyl groups, there are added a carbodiimide compound (B) in an amount of 0.3 to 1.5 equivalents of the carbodiimide functional group when the amount of carboxyl terminal group in the polybutylene terephthalate resin (A) is set as 1, 20 to 100 parts by weight of a fibrous filler (C), and 5 to 15 parts by weight of an elastomer (D).
