Abstract
The present invention provides a polybutylene terephthalate resin composition having both low warpage and high durability in a cold cycle environment. 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 2 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 15 to 65 parts by weight of a thermoplastic resin (D) of one or more selected from polycarbonate resin and polyethylene terephthalate resin.
