Disclosed are a carbon nanotube dispersion liquid that suppresses aggregation of carbon nanotubes and exhibits high dispersion stability, and a carbon nanotube / rubber composite that uses the carbon nanotube dispersion liquid and that has excellent electrical conductivity. A carbon nanotube / rubber composite is obtained by blending a rubber latex into a carbon nanotube dispersion comprising carbon nanotubes, sodium alkyldiphenyloxide disulfonate as a surfactant, and a dispersion medium, followed by salting out. . The carbon nanotubes preferably have an average diameter Av and a diameter distribution 3σ of 0.60> 3σ / Av> 0.20. The dispersion medium is preferably water. [Selection figure] None |
