Abstract: The present invention provides a method for further uniformly drawing out a carbon nanotube web while inhibiting mixing of edge scraps. A carbon nanotube web is drawn out from a carbon nanotube array-in a state in which abutting members which abut on the carbon nanotube array are provided on respective outer sides of both edges of a boundary region between the carbon nanotube array and the carbon nanotube web.

Abstract: The method for producing a carbon nanotube web includes preparing a carbon nanotube array disposed on a substrate, the carbon nanotube array including a plurality of carbon nanotubes vertically aligned relative to the substrate; and drawing a carbon nanotube web from the carbon nanotube array so that the plurality of carbon nanotube single yarns are arranged in parallel, wherein in the step of drawing a carbon nanotube web, the carbon nanotube web is oscillated in a direction crossing both the thickness direction of the substrate and the drawing direction of the carbon nanotube web.

Abstract: A method for producing a carbon nanotube web includes a step of preparing a carbon nanotube array disposed on a substrate, the carbon nanotube array including a plurality of carbon nanotubes vertically aligned relative to the substrate; and a step of drawing a carbon nanotube web from the carbon nanotube array, the carbon nanotube web including a plurality of carbon nanotube single yarns arranged in parallel in a direction intersecting the direction carbon nanotube single yarns extend, and the carbon nanotube single yarns including a plurality of continuously connected carbon nanotubes. In the step of drawing a carbon nanotube web, the drawing position of the carbon nanotube web from the carbon nanotube array is kept at the same position in the drawing direction of the carbon nanotube web.
