PROBLEM TO BE SOLVED: To provide a method for producing a carbon nanotube dispersion where the dispersibility of a carbon nanotube is enhanced while relaxing the condition of agitation.SOLUTION: The method for producing the carbon nanotube dispersion includes an agitating step to obtain a mixed liquid by agitating the carbon nanotube and a dispersant in a dispersing medium and an ultrasonic wave irradiating step to irradiate the mixed liquid with ultrasonic waves. The agitating step is performed under reduced pressure. For example, a cellulose-based polymer is used as the dispersant. For example, an aqueous dispersing medium is used as the dispersing medium. |
