An object of the present invention is to provide a polybutylene terephthalate resin material which maintains high welding strength and has excellent durability in cold and heat cycle environment when joined each other by heat welding method. The polybutylene terephthalate resin composition for welding contains 100 parts by weight of (A) a polybutylene terephthalate resin having a terminal carboxyl group content of 30 meq/kg or less; (B) a carbodiimide compound in an amount such that the content of the carbodiimide functional group is 0.3 to 1.5 equivalent when the terminal carboxyl group content of the (A) polybutylene terephthalate resin is defined as 1; and 0 to 15 parts by weight of (C) an elastomer. |
