The present invention relates to a thermoplastic resin composition and a molded product using the same. In particular, the thermoplastic resin composition comprises: (A) a polyester resin; (B) a styrene-based copolymer; (C) a rubber-modified vinyl-based graft copolymer; and (D) glass fibers. The polyester resin (A) comprises (A-1) a polybutylene terephthalate resin having an intrinsic viscosity of 1.1 dl/g or less, and (A-2) a polyethylene terephthalate resin having an intrinsic viscosity of 1.0 dl/g or less. The glass fibers (D) comprise (D-1) first glass fibers having a length of 2-4 mm, and (D-2) second glass fibers having a length 10-100 μm. (A) 폴리에스테르 수지, (B) 스티렌계 공중합체, (C) 고무 변성 비닐계 그라프트 공중합체, 및 (D) 유리섬유를 포함하고, 상기 폴리에스테르 수지(A)는 (A-1) 고유 점도가 1.1 dl/g 이하인 폴리부틸렌 테레프탈레이트 수지 및 (A-2) 고유 점도가 1.0 dl/g 이하인 폴리에틸렌 테레프탈레이트 수지를 포함하고, 상기 유리섬유(D)는 (D-1) 길이가 2 mm 내지 4 mm인 제1 유리섬유 및 (D-2) 길이가 10 ㎛ 내지 100 ㎛인 제2 유리섬유를 포함하는 열가소성 수지 조성물, 및 이를 이용한 성형품에 관한 것이다.
