Abstract
Provided is a means for obtaining a polybutylene terephthalate resin composition that exhibits excellent hydrolysis resistance and high fluidity in a molten state. A carbodiimide compound (B) and a polyhydric hydroxyl group-containing compound (C) are added to a polybutylene terephthalate resin (A) having a terminal carboxyl group content of 30 meq/kg or lower. The polyhydric hydroxyl group-containing compound (C) that is used has a hydroxyl group value of 200 or higher. It is preferable for the polybutylene terephthalate resin (A) to have an intrinsic viscosity of 0.6 dL/g or higher.
