Abstract
Provided is a conductor film obtainable using a carbon nanotube dispersion liquid. The carbon nanotube dispersion liquid contains carbon nanotubes (A), a polymeric dispersant (B) including a sulfonic acid group-containing monomeric unit and an ethylenically unsaturated aliphatic carboxylic acid monomeric unit, and a solvent (C). Percentage content of the ethylenically unsaturated aliphatic carboxylic acid monomeric unit in the polymeric dispersant (B) is greater than 20 mol % and no greater than 90 mol %.
