Abstract
The object of the present invention is to provide carbon fiber material having high electrical conductivity at a low cost. A manufacturing method of carbon fiber material comprises a dispersion liquid preparation step, a centrifugal spinning step and a denaturation step. The dispersion liquid preparation step is a step in which dispersion liquid containing resin and carbon particles is prepared. The centrifugal spinning step is a step in which nonwoven fabric made of a carbon fiber precursor is formed from the dispersion liquid. The denaturation step is a step in which the carbon fiber precursor denatures into carbon fiber.
