(57) [Summary] [Problem] A molding cycle is short, excellent in productivity, high in stability against hydrolysis, there is no corrosion of electrical contacts, and Provided are a polybutylene terephthalate resin composition and a molded article which can be suitably used for a wide range of uses such as automobile parts and electric / electronic parts, in which coloring and reduction in mechanical properties at a high temperature are suppressed. A cooling crystallization temperature measured by a differential scanning calorimeter at a cooling rate of 20 ° C./min is 175 ° C. or more, a terminal carboxyl group content is 30 eq / t or less, or a residual tetrahydrofuran content is 300 ppm (weight ratio) or less. A polybutylene terephthalate resin composition comprising the polybutylene terephthalate and a phenolic antioxidant, and a molded article obtained by molding the polybutylene terephthalate resin composition. |
