PROBLEM TO BE SOLVED: To provide a method for producing a carbon nanotube wire that has excellent conductivity, reduced variations, high productivity, and capability of mass production.SOLUTION: A method for producing a CNT wire includes forming a CNT wire by twisting together a plurality of carbon nanotubes having a layered structure of one or more layer (step S12), refining the CNT wire (step S13), and doping the refined CNT wire with a dissimilar element (step S14).SELECTED DRAWING: Figure 4 【課題】良好な導電性を有すると共に、ばらつきを抑え、生産性が高く量産に優れたカーボンナノチューブ線材の製造方法を提供する。【解決手段】ＣＮＴ線材の製造方法は、１層以上の層構造を有する複数のカーボンナノチューブを撚り合わせてＣＮＴ線材を形成し（ステップＳ１２）、該ＣＮＴ線材を精製し（ステップＳ１３）、精製後のＣＮＴ線材に異種元素をドープする（ステップＳ１４）。【選択図】図４
