Abstract
A conductive material dispersion containing a conductive material containing carbon fibers, a dispersant, and a dispersion medium, in which the dispersant contains a copolymer A containing a nitrile group-containing structural unit and an aliphatic hydrocarbon structural unit, and a Mooney viscosity (ML, 100° C.) of the copolymer A is 40 to 70, and the conductive material dispersion has a phase angle of 19° or greater at a frequency of 1 Hz.
