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&#xb0; C.) of the copolymer A is 40 to 70, and the conductive material dispersion has a phase angle of 19&#xb0; or greater at a frequency of 1 Hz.

Conductive material dispersion, binder resin-containing conductive material dispersion, slurry for electrode film, electrode film, and non-aqueous electrolyte secondary battery

A conductive material dispersion containing a conductive material containing carbon fibers, a dispersant, and an amide-based organic solvent, in which the dispersant contains a copolymer A containing a nitrile group-containing structural unit and satisfies following conditions. (I) A pH of the conductive material dispersion is 9.0 or greater. (II) A phase angle of the conductive material dispersion at a frequency of 1 Hz obtained by dynamic viscoelasticity measurement is 19&#xb0; or greater, and a complex elastic modulus of the conductive material dispersion obtained by dynamic viscoelasticity measurement is less than 20 Pa.
