Abstract
The method for producing a carbon nanotube yarn includes preparing a vertically-aligned carbon nanotube that is disposed on a substrate and is aligned vertically to the substrate; preparing a rotating body having a groove on a circumferential face; drawing a plurality of carbon nanotubes from the vertically-aligned carbon nanotube continuously and linearly to prepare a carbon nanotube single yarn, and arranging the plurality of carbon nanotube single yarns in parallel to prepare a carbon nanotube web; winding the carbon nanotube web around the circumferential face of the rotating body so as to fit in the groove; and drawing the carbon nanotube web from the rotating body.
