The present invention provides a conductive material dispersion, a slurry for an electrode film, an electrode film, and a nonaqueous electrolyte secondary battery capable of achieving both good dispersibility and stability. Conductive material dispersion, comprising a conductive material containing carbon fibers, a dispersant, and an amide-based organic solvent, in the conductive material dispersion, the dispersant includes a copolymer A, and the copolymer A contains a structural unit containing a nitrile group , and the conductive material dispersion satisfies the following conditions: (I) the pH of the conductive material dispersion is more than 9.0; The phase angle is more than 19°, and the complex elastic modulus is less than 20Pa. |
