1. A method for producing a carbon nanofiber composite, comprising bringing at least one catalyst and at least one particulate carbon material as a fluidizing dispersant which imparts fluidity to the catalyst into contact with at least one gas containing at least one gaseous carbon-containing compound, while mechanically stirring the catalyst and the particulate carbon material in a state that the catalyst is fluid with respect to the particulate carbon material in a reactor, and
wherein the particulate carbon nanofiber composite comprises 70% by volume and more of particles within (i) a particle diameter of 1 μm or less, and (ii) a median diameter D50 by volume of 1 μm or less.
