3 Claims

1. A polybutylene terephthalate resin composition comprising:

84 to 95 parts by mass of a polybutylene terephthalate resin (A) having an intrinsic viscosity (IV) of 0.60 to 0.95 dl/g, 3 to 9 parts by mass of a modified olefin resin (B), 1 to 13 parts by mass of a polyester elastomer (C), and 0.1 to 1.2 parts by mass of a carbodiimide compound (D), based on 100 parts by mass of components (A), (B) and (C) in total,
