Zusammenfassung:There is provided a carbon material dispersion which has excellent dispersibility and in which the dispersibility is retained stably over a long period of time even when the carbon material dispersion contains a carbon material at a high concentration. The carbon material dispersion is a carbon material dispersion containing a carbon material, water, and a polymeric dispersant, wherein the polymeric dispersant is a polymer including 5 to 40% by mass of a constituent unit (1) derived from a monomer 1, such as 2-vinylpyridine, 50 to 80% by mass of a constituent unit (2) derived from a monomer 2 represented by formula (1) (wherein R1 represents a hydrogen atom or the like, A represents O or NH, X represents an ethylene group or a propylene group, Y represents O, NHCOO, or NHCONH, each of R2 represents a hydrogen atom or the like, n represents 20 to 100, and R3 represents a hydrogen atom or the like), and 0.5 to 40% by mass of a constituent unit (3) derived from a monomer 3 copolymerizable with above-described monomers.
