It is an object of the present invention to provide a CNT having a thin film thickness, which exhibits the inherent properties of CNT, and which does not form a bundle, and to provide an efficient manufacturing method thereof. A method for producing a carbon nanotube having a band-like shape by being pressed and flattened in its entire length or a part thereof, characterized in that as a powder of an organic compound calcined to contain residual hydrogen, And a catalyst which may be other than the above-mentioned metal, or other elements may be supported on the support, and this may be placed in an airtight container made of a heat resistant material and subjected to hot isostatic pressing using the pressurized gas atmosphere in the container, Wherein the maximum attained temperature in the pressure treatment is 750 to 1200 占 폚. |
