The present invention provides a method for improving the conductivity of a CNT-dispersed material prepared from a CNT-containing composition using a highly branched polymer excellent in CNT dispersibility as a dispersant, that is, a conductive composite. A carbon nanotube dispersion material containing carbon nanotubes and a hyperbranched polymer having a glass transition point is heated at a temperature in the range of −30 ° C. to + 150 ° C. of the glass transition point of the hyperbranched polymer, for example. A method for improving the conductivity of a carbon nanotube dispersion material. [Selection figure] None |
