Summary: | There is provided a carbon material dispersion in which a carbon material containing a carbon nanotube is dispersed favorably without substantially producing a coarse aggregate irrespective of liquid compositions and dispersion methods, the carbon material dispersion excellent in viscosity stability. The carbon material dispersion excluding one that contains a volatile salt contains: a carbon material containing a carbon nanotube; a liquid medium; and a dispersant. The content of the dispersant in terms of solid content based on 100 parts by mass of the carbon material is 204 parts by mass or less, and when a dilute dispersion is obtained by diluting the carbon material dispersion with a diluent comprising the liquid medium such that absorbance at a wavelength WM, which is a median value of an arbitrary wavelength WL within a range of 350 to 550 nm and an arbitrary wavelength WH within a range of 650 to 850 nm, is 1.8±0.02, a ratio of absorbance AL at the wavelength WL to absorbance AH at the wavelength WH, (AL/AH), is 1.60 or more for the dilute dispersion. |
