The present invention relates to a thermoplastic resin composition for blow molding and a molded article using the same. The thermoplastic resin composition for blow molding comprises: 100 parts by weight of a basic resin including (A) 20 to 40 wt% of a diene graft copolymer, (B) 10 to 20 wt% of an aromatic vinyl compound-cyanide vinyl compound copolymer, (C) 30 to 50 wt% of an alpha-methyl styrene copolymer and (D) 10 to 20 wt% of an N-phenyl maleimide copolymer; and (E) 0.1 to 3 parts by weight of inorganic particles which are zinc sulfide, titanium dioxide, talc or a combination thereof. Not only surface quality of a molded article can be improved but thermal resistance and flowability can be secured. (A) 디엔계 그라프트 공중합체 20 내지 40 중량%, (B) 방향족 비닐 화합물-시안화 비닐 화합물 공중합체 10 내지 20 중량%, (C) 알파-메틸스티렌 공중합체 30 내지 50 중량%, 및 (D) N-페닐말레이미드 공중합체 10 내지 20 중량%를 포함하는 기초 수지 100 중량부; 그리고 상기 기초 수지 100 중량부에 대해 (E) 황화아연, 이산화티탄, 탈크, 또는 이들의 조합인 무기입자 0.1 내지 3 중량부를 포함하는 블로우 몰딩용 열가소성 수지 조성물, 그리고 이를 이용한 성형품에 관한 것이다.
