The present invention provides a conductive composite comprising: a thermoplastic polymer; a carbon nanotube; and a conductivity-improving additive, wherein the conductivity-improving additive comprises two or more selected from among a phenol-based compound, a phosphate-based compound, and a polyalkylene-based wax compound. Thus, it is possible to provide a conductive composite having remarkably improved conductivity by reducing the surface resistance while maintaining the basic physical properties of a thermoplastic polymer resin. La présente invention concerne un composite conducteur comprenant : un polymère thermoplastique ; des nanotubes de carbone ; et un additif améliorant la conductivité, l'additif améliorant la conductivité comprenant au moins deux éléments choisis parmi un composé à base de phénol, un composé à base de phosphate, et un composé cire à base de polyalkylène. Il est ainsi possible de produire un composite conducteur possédant une conductivité remarquablement améliorée par réduction de la résistance surfacique tout en maintenant les propriétés physiques de base d'une résine polymère thermoplastique. 본 발명은, 열가소성 고분자; 탄소나노튜브; 및 전도성 개선용 첨가제를 포함하되, 전도성 개선용 첨가제로서 페놀계 화합물, 포스파이트계 화합물 및 폴리알킬렌계 왁스 화합물 중에서 선택되는 둘 이상을 포함하는 전도성 복합재를 제공한다. 열가소성 고분자 수지가 갖는 기본적인 물성을 유지하면서, 표면저항을 감소시켜 전도성이 현저히 향상된 전도성 복합재를 제공 할 수 있다.
