Abstract
Provided is a conductive material dispersion including: a conductive material containing at least one kind selected from the group consisting of a carbon nanotube and carbon black; carboxymethyl cellulose or its salt; and water. The carboxymethyl cellulose or its salt has a weight average molecular weight of 10,000 to 150,000 and an etherification degree of 0.5 to 0.9. A product of the complex elastic modulus (Pa) and the phase angle (°) of the conductive material dispersion is 100 or more and 1,500 or less.
