A carbon nanofiber dispersion liquid having an excellent dispersibility and dispersion stability. Also, coating paste compositions including the carbon nanofibers produced by using the dispersion liquid are provided. The carbon nanofiber dispersion liquid includes: a solvent; a carbon nanofiber; an alkanolamine; and a chelating agent. Preferably, in the carbon nanofiber dispersion liquid, the alkanolamine is at least one selected from a group consisting of monoisopropanolamine, diisopropanolamine, and triisopropanolamine. Also, in the carbon nanofiber dispersion liquid, the chelating agent is at least one selected from a group consisting of an aminocarboxylic acid chelating agent, a phosphonic acid chelating agent, a gluconic acid chelating agent, and an organic acid. |
