Abstract
A carbon nanohorn carried material for producing a carbon nanotube by a chemical vapor deposition (CVD) method, including a catalytic metal or a compound thereof contained inside carbon nanohorns or supported on exterior walls of the carbon nanohorns is provided. A carbon nanotube is produced by a CVD reaction using the carbon nanohorn carried material. A novel technical means for producing a carbon nanotube which does not use any noncarbon type carrier, can easily collect and purify the carbon nanotube and can control the length of the carbon nanotube can be provided.
