Abstract
Provided is a surface-treated carbon nanotube having few surface fractures, not reducing the molecular weight of the resin to be mixed and having excellent extrudability. In the surface-treated carbon nanotube, the thermal reduction amount at 600° C. in a nitrogen atmosphere is 0.2 to 40%, the surface oxygen concentration measured by X-ray photoelectron spectroscopy (XPS) is 1.5 to 40 atm % and the surface sulfur concentration is less than 0.1 atm %.
