A conductive carbon material dispersion containing a conductive carbon material, a cationic dispersant and a solvent, and not containing an anionic compound, wherein the cationic dispersant is, for example, an anion such as a dicyandiamide / diethylenetriamine condensate or polyethyleneimine. The conductive carbon material dispersion, which is a cationic polymer having no functional group, is suitable for producing an undercoat layer formed on an electrode current collector of an energy storage device such as a lithium ion secondary battery. |
