1. A method for manufacturing a carbon nanotube comprising:
a mist generating step of generating a mist including a catalyst particle and a liquid carbon source;
a growing step of growing a carbon nanotube from the catalyst particle by heating the mist; and
a drawing step of drawing the carbon nanotube that is obtained in the growing step by applying a tensile force to the carbon nanotube, wherein the tensile force is applied to the carbon nanotube in a direction toward a downstream side by varying a carrier gas in flow velocity by making an average flow velocity of the carrier gas on the downstream side larger than an average flow velocity of the carrier gas on an upstream side.
