Abstract
A method for manufacturing a carbon nanotube includes: 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.
