CONDUCTIVE MATERIAL DISPERSION AND USE OF CONDUCTIVE MATERIAL DISPERSION

A conductive material dispersion containing a dispersant that satisfies the following (1) and (2), a carbon-based conductive material (C), and a medium (D) containing at least water. (1) Contains a polymer (A) having one or more selected from the group consisting of nitrile group-containing structural units, carboxyl group-containing structural units, hydroxyl group-containing structural units, and heterocycle-containing structural units and having a weight average molecular weight of 5,000 or more and 360,000 or less. (2) Contains a component (B) other than a polymer and derived from the raw materials of the polymer (A); and the content of the component (B) is 2 mass% or less based on the total mass of the dispersant.
