Abstract

To provide a new carbon nanotube dispersion having good dispersibility.SOLUTION: A carbon nanotube dispersion of the present invention comprises: at least a carbon nanotube, a solvent, and polyvinyl acetal. The ratio of an intensity of a peak at 2950 cm-1 to an intensity of a peak at 1650 cm-1 in FT-IR spectrum of the polyvinyl acetal obtained by ATR method is 50 or more. The mass average molecular weight of the polyvinyl acetal measured by gel permeation chromatography is 100,000 or less.SELECTED DRAWING: None
