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° or greater, and a complex elastic modulus of the conductive material dispersion obtained by dynamic viscoelasticity measurement is less than 20 Pa.
