Abstract
A carbon nanostructure producing method includes a growth step in which a plurality of catalyst particles in close contact with each other are separated in a flow of a carbon-containing gas so as to grow carbon nanotubes between the plurality of catalyst particles, and an elongation step in which the carbon nanotube is elongated by a wind pressure of the carbon-containing gas with at least one of the catalyst particles being retained.
