(KR10-2010459) Provided is a carbon nanotube pellet. According to the present invention, the carbon nanotube pellet is produced by using a small amount of solvents and ensures increased apparent density. By using pellet-like carbon nanotubes in the production of composite materials rather than powdery carbon nanotubes, it is possible to bring improvement on issues regarding safety and changes in content due to scattering of powder. Since the carbon nanotube pellet has higher density than powdery forms, the carbon nanotube pellet ensures easy transfer and improvement, thereby being effectively applied to the production of composite materials.
