Method and apparatus for manufacturing carbon nanotube assembled wire

A method for manufacturing a carbon nanotube assembled wire, comprising:

• a first step of supplying a carbon-containing gas at one, first end of a tubular carbon nanotube synthesis furnace and heating the carbon nanotube synthesis furnace by a heater provided on an outer circumference of the carbon nanotube synthesis furnace to grow a carbon nanotube from each of a plurality of catalyst particles suspended in the carbon nanotube synthesis furnace to synthesize a plurality of carbon nanotubes;
• a second step of orienting the plurality of carbon nanotubes in a longitudinal direction of the carbon nanotubes in a first channel provided in the carbon nanotube synthesis furnace, and thus assembling them together, to form the carbon nanotube assembled wire;
• and
• a third step of collecting the carbon nanotube assembled wire at a second end of the carbon nanotube synthesis furnace opposite to the first end,
• an adhesion suppressing gas stream being generated from an adhesion suppressing gas discharge port located between the second end and an end of the heater closer to the second end, the adhesion suppressing gas stream flowing between an internal wall of the carbon nanotube synthesis furnace and an external wall of the first channel in a direction from the second end toward the first end to suppress adhesion of the plurality of carbon nanotubes to the internal wall of the carbon nanotube synthesis furnace.
