Abstract: Provided are a carbon fiber composite material and a producing method thereof comprising an adhesive layer having excellent conductivity and high peeling strength. A carbon fiber composite material according to the present application includes a first carbon fiber dispersion layer having carbon fibers dispersed in a thermosetting resin, a carbon nanotube dispersion layer having carbon nanotubes dispersed in a thermosetting resin, and a second carbon fiber dispersion layer having carbon fibers dispersed in a thermosetting resin, wherein the carbon nanotube dispersion layer is arranged between the first carbon fiber dispersion layer and the second carbon fiber dispersion layer, and the carbon nanotubes in the carbon nanotube dispersion layer are arranged in close contact with the carbon fibers of the first carbon fiber dispersion layer and the carbon fibers of the second carbon fiber dispersion layer.
