Claim 7:
8. A conductive material dispersion comprising:
a dispersant composition for carbon nanotubes comprising:
a copolymer that includes a structural unit A represented by the following general formula (1) and a structural unit B represented by the following general formula (2); and
a solvent,
wherein the content of the structural unit B in all structural units of the copolymer is 20 mass % or more:, where R1, R2, R3, R5, R6, and R7 are the same or different from each other and are each a hydrogen atom, a methyl group, or an ethyl group, R4 is a hydrocarbon group having 16 to 30 carbon atoms, R8 is a linear or branched alkylene group having 2 to 3 carbon atoms, X1 is an oxygen atom or NH, X2 is an oxygen atom, p is the number of 1 to 8, and R9 is a hydrogen atom, a methyl group, or an ethyl group,
wherein, in the structural unit B represented by the general formula (2), a structural unit b1 in which X2 is an oxygen atom, p is 1, and R9 is a hydrogen atom accounts for 50 mass % or more of the total amount of the structural unit B; and
carbon nanotubes.
