<P>PROBLEM TO BE SOLVED: To provide a method for producing a carbon nanotube in which a long carbon nanotube is easily produced, in a method of bringing a mixture containing a raw material carbon component into contact with a catalyst particle. Ž<P>SOLUTION: The production method includes bringing a mixture containing a raw material carbon component into contact with a catalyst particle 55 to grow a carbon nanotube 57 from the catalyst particle 55 by the raw material carbon component in the mixture. The mixture is brought into contact with an immobilizing material 41 for immobilizing a component other than the raw material carbon component or a component which reduces catalytic activity in the mixture, thereby reducing the component other than the raw material carbon component or the activity-reducing component in the mixture to increase the existence ratio of the raw material carbon component before growing the carbon nanotube 57.
