Abstract
A method of producing a carbon nanotube aqueous dispersion having satisfactory dispersibility. The method of producing a carbon nanotube aqueous dispersion includes: preparing mixed liquids by mixing carbon nanotubes, carboxymethyl cellulose and water; and dispersing the carbon nanotubes contained in the mixed liquids by an aqueous counter collision method, wherein a ratio of a mass of the carboxymethyl cellulose to a mass of the carbon nanotubes in the mixed liquids is 1/7 or more.
