Method for manufacturing carbon nanotube, method for manufacturing carbon nanotube assembled wire, method for manufacturing carbon nanotube assembled wire bundle, carbon nanotube manufacturing apparatus, carbon nanotube assembled wire manufacturing apparatus, and carbon nanotube assembled wire bundle manufacturing apparatus

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

• a growing step of growing a plurality of carbon nanotubes by supplying a carbon-containing gas to a plurality of catalyst particles in a suspended state to grow one or a plurality of carbon nanotubes from each of the plurality of catalyst particles;
• a drawing step of drawing the plurality of carbon nanotubes by applying a tensile force to the plurality of carbon nanotubes in a suspended state;
• and
• an assembling step of obtaining a carbon nanotube assembled wire by orienting and assembling the plurality of carbon nanotubes in the suspended state in a direction along flow of the carbon-containing gas.
