PURPOSE: Provided is a polyethylene terephthalate resin composition, which has excellent light blocking property and a high crystallization degree even at a mold temperature of 100 deg.C or less so that it can be easily injection molded. CONSTITUTION: The polyethylene terephthalate(PET) resin composition comprises a PET resin as a main component, a fiber reinforcing agent, a nucleating agent, a release agent, and a heat-resistant agent. The PET resin composition further comprises 1-10 parts by weight of a PET-salt and 0.5-2.0 parts by weight of a metal acetate, based on 100 parts by weight of the PET resin. Particularly, the PET-salt is at least one salt selected from the group consisting of compounds of formula 1 and formula 2, wherein M is a monovalent or divalent metal, and n is an integer of 5-50.
