Abstract

The present invention relates to a carbon nanotube dispersion comprising carbon nanotubes, a dispersant and a dispersion medium, wherein the dispersant comprises a first dispersant and a second dispersant in a weight ratio of 100:10 to 100:90, the first dispersant is a dispersant comprising an N atom, the second dispersant is a compound comprising a sulfonic acid group, a hydroxyl group and an aromatic ring in a molecular structure, and a weight ratio of the carbon nanotubes and the dispersant is 100:50 to 100:500, thereby having low viscosity and a little change in viscosity over time.
