1. A method for manufacturing a carbon nanotube, the method comprising:
a growing step of growing a carbon nanotube from a catalyst particle by supplying a carbon-containing gas to the catalyst particle in a suspended state; and
a drawing step of drawing the carbon nanotube by applying a tensile force to the carbon nanotube in a suspended state,
wherein the tensile force is applied to the carbon nanotube by varying a flow velocity of the carbon-containing gas, and
wherein an average flow velocity of the carbon-containing gas at a downstream side is higher than an average flow velocity of the carbon-containing gas at an upstream side.
