<p>The present invention addresses the problem of providing: a carbon nanotube composite material which has excellent uniformity and high thermal conductivity; and a heat conductor. A carbon nanotube composite material of the present invention has a carbon nanotube group, which is configured of a plurality of carbon nanotubes, present between adjacent carbon fibers. The carbon fibers have an average diameter of from 1 mum to 50 mum (inclusive); the carbon nanotubes have an average diameter of from 0.7 nm to 50 nm (inclusive); the carbon nanotubes are contained in an amount within the range from 0.01% by weight to 30% by weight (inclusive) and the carbon fibers are contained in an amount within the range from 10% by weight to 60% by weight (inclusive), respectively relative to 100% by weight of the carbon nanotube composite material; the thermal conductivity of the matrix material is less than 10 W/mk; and the carbon nanotube composite material has a direction in which the thermal conductivity is 10 W/mK or more.</p> |
