Claim 16:
17. A method for manufacturing a carbon nanotube assembled wire bundle comprising:
a mist generating step of generating a mist including a plurality of catalyst particles and a liquid carbon source;
a growing step of growing one or more carbon nanotubes from each of the plurality of catalyst particles by heating the mist;
an assembling step of obtaining a plurality of carbon nanotube assembled wires by orienting and assembling the carbon nanotubes in their longitudinal direction; and
an obtaining step of obtaining a carbon nanotube assembled wire bundle by orienting and bundling the plurality of carbon nanotube assembled wires in their longitudinal direction, wherein:
in the growing step, the carbon nanotubes pass through a first flow channel,
in the assembling step, the carbon nanotubes pass through one or more second flow channels located downstream of the first flow channel, and the one or more second flow channels each have an area in cross section smaller than an area in cross section of the first flow channel.
