PURPOSE: Provided is an improved polybutylene terephthalate(PBT) resin composition which prevents the gelation of the PBT resin, and has excellent long-term heat resistance and heat/moisture resistance. CONSTITUTION: The composition comprises (A) 40-90 wt% of PBT resin, (B) 0.1-10.0 wt% of epoxy compound having an epoxy group, (C) 0.1-10.0 wt% of epoxy compound having two epoxy groups, (D) 0.01-5.0 wt% of catalyst for accelerating a reaction of the epoxy and terminal group of the PBT resin, (E) 1.0-30 wt% of brominated polycarbonate oligomer, (F) 1.0-10 wt% of antimony trioxide, and (G) 3-50 wt% of glassfiber and mineral filler, wherein the 3-50 wt% is based on the sum of (A),(B),(C),(D),(E), and (F).
