Abstract
The present invention relates to a polybutylene terephthalate resin composition comprising 20 to 50 mass % of a polybutylene terephthalate resin (A) having an intrinsic viscosity of 0.60 to 1.0 dl/g, 20 to 45 mass % of a fibrous filler (B), 1 to 20 mass % of a polycarbonate resin (C) having a melt volume rate (MVR) of 30 cm/10 min or more, 3 to 20 mass % of a copolymerized polybutylene terephthalate resin (D), and 0 to 20 mass % of an inorganic filler (E) other than the fibrous filler (B). The polybutylene terephthalate resin composition can form a molding that remedies sink marks, maintains high heat deflection temperature, and has excellent appearance.
