To provide a production method capable of obtaining a high quality long object whose material is a carbon nanotube.SOLUTION: The production method includes: (1) a process of obtaining a first web 10a by gradually drawing a carbon nanotube from a first array; (2) a process of retaining the first web 10a to a first retainer 12a by attaching a part of the first web 10a to the first retainer 12a; (3) a process of obtaining a second web 10b by gradually drawing the carbon nanotube from a second array; (4) a process of retaining the second web 10b to a second retainer 12b by attaching a part of the second web 10b to the second retainer 12b; and (5) a process of forming a joint by overlapping a vicinity to the first retainer 12a of the first web 10a and a vicinity to the second retainer 12b of the second web 10b together while a width direction of the first web 10a substantially coincides with a width direction of the second web 10b.SELECTED DRAWING: Figure 10 【課題】材質がカーボンナノチューブであり高品質な長尺物が得られる製造方法の提供。【解決手段】（１）第一アレイからカーボンナノチューブを徐々に引き出して、第一ウェブ１０ａを得る工程、（２）上記第一ウェブ１０ａの一部を第一保持具１２ａに当接させて、この第一保持具１２ａにこの第一ウェブ１０ａを保持する工程、（３）第二アレイから上記カーボンナノチューブを徐々に引き出して、第二ウェブ１０ｂを得る工程、（４）上記第二ウェブ１０ｂの一部を第二保持具１２ｂに当接させて、この第二保持具１２ｂにこの第二ウェブ１０ｂを保持する工程、及び（５）上記第一ウェブ１０ａの幅方向と上記第二ウェブ１０ｂの幅方向とが実質的に一致する状態で、上記第一ウェブ１０ａの上記第一保持具１２ａの近傍と、上記第二ウェブ１０ｂの上記第二保持具１２ｂの近傍とを重ね合わせ、ジョイントを形成する工程を含む。【選択図】図１０
