Abstract
A method of the present invention for producing a carbon nanotube includes: a dispersing step of dispersing a carbon nanotube in a solvent by carrying out a dispersion treatment that brings about a cavitation effect, the carbon nanotube having an average diameter (Av) and a diameter distribution (3σ) that satisfy 0.60>3σ/Av>0.20; and a mixing step of mixing carbon nanotube slurry obtained in the dispersing step with latex.
