Disclosed herein is a cyclic dispersant having a rigid block which has a high affinity for carbon nanotubes, and a flexible block which has a high affinity for a solvent, with a linkage created therebetween. Having a structure that is advantageous with respect to adsorption to carbon nanotubes, the dispersant, even if used in a small amount, can disperse a large amount of carbon nanotubes. |
