An object is to provide methods for producing a carbon nanotube dispersion paste and a mixture paste that are excellent in pigment dispersibility and storage stability even at a high pigment concentration, and another object is to provide an electrode layer for a lithium ion secondary battery excellent in various properties (e.g., conductivity and battery performance). Provided as a solution is a method for producing a carbon nanotube dispersion paste, the method including a step of mixing and dispersing components including a dispersing resin (A) having a heterocyclic ring and/or an alkyl group having 12 or more carbon atoms, a carbon nanotube (B), a solvent (C) having a water content of less than 10000 ppm, and polyvinylidene fluoride (D) that can be optionally included, wherein the carbon nanotube dispersion paste has a water content of less than 10000 ppm.
A method for producing a carbon nanotube dispersion paste, the method being characterized by comprising a step of mixing and dispersing components including a dispersing resin (A) having a heterocyclic ring and/or an alkyl group having 12 or more carbon atoms, a carbon nanotube (B), a solvent (C) having a water content of less than 10000 ppm, and polyvinylidene fluoride (D) that can be included as needed, wherein the carbon nanotube dispersion paste has a water content of less than 10000 ppm.
