    Abstract: A polybutylene terephthalate resin composition in which it is possible to effectively suppress discoloration without lowering the heat shock resistance. The polybutylene terephthalate resin composition is part of a molded article having a lightness L* value of 80 or higher as measured using a color difference meter, and includes a polybutylene terephthalate resin having a terminal carboxyl group content of 30 meq/kg or less, a carbodiimide compound, and a phosphite compound; and the phosphite compound content is 0.05-0.15 parts by mass per 100 parts by mass of polybutylene terephthalate resin.

    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.
