The present invention relates to a thermoplastic resin composition, and a molded article using the same. The thermoplastic resin composition comprises: a base resin comprising (A) 15-25 wt% of an acrylonitrile-butadiene-styrene graft copolymer, (B) 45-65 wt% of an aromatic vinyl-cyanide vinyl copolymer having a weight average molecular weight of 150,000 to 250,000 g/mol, and (C) 20-30 wt% of a maleimide-based copolymer; (D) 0.2-0.8 parts by weight of an ethylene-alkyl acrylate-based copolymer; and (E) 1-3 parts by weight of an ethylene-vinyl acetate copolymer, based on 100 parts by weight of the base resin. The thermoplastic resin composition is excellent in both heat resistance and heat fusion properties. (A) 아크릴로니트릴-부타디엔-스티렌 그라프트 공중합체 15 내지 25 중량%; (B) 중량평균분자량이 150,000 내지 250,000 g/mol인 방향족 비닐-시안화 비닐 공중합체 45 내지 65 중량%; 및 (C) 말레이미드계 공중합체 20 내지 30 중량%를 포함하는 기초수지 100 중량부에 대해, (D) 에틸렌-알킬 아크릴레이트계 공중합체 0.2 내지 0.8 중량부; 및 (E) 에틸렌-비닐 아세테이트 공중합체 1 내지 3 중량부를 포함하는 열가소성 수지 조성물, 및 이를 이용한 성형품에 관한 것이다.
