Carbon nanotube pellets, provided according to the present invention, is manufactured using only a small quantity of a solvent and have increased apparent density. The present invention uses carbon nanotubes in a pellet form rather than in a powder form to manufacture a composite material thereby improving the problems of change in content and safety due to scattering powder, and has higher density than the powder form to be easier to transport, carry, and enhance, thereby allowing more effective application in manufacturing of the composite material.
