Method for producing a carbon nanotube dispersion liquid and conductive films

Carbon nanotube-containing composition, a weight-average molecular weight 01,000 or more 400,000 or less of a dispersing agent, a carbon nanotube dispersion containing the volatile salt and water-based solvent. The present invention provides a carbon nanotube dispersion liquid is possible to maintain high dispersibility of carbon nanotubes be dispersed material using amount less than before.
