An object of the present invention is to provide composite carbon fibers in which multiwalled carbon nanotubes are homogeneously dispersed between graphitized carbon nanofibers and near the surface of the graphitized carbon nanofibers, the composite carbon fibers being capable of easily being dispersed in a matrix such as resin without leaving aggregates, and also imparting low resistance. Disclosed are composite carbon fibers comprising multiwalled carbon nanotubes having a fiber diameter of 5 nm or more and 30 nm or less and graphitized carbon nanofibers having a fiber diameter of 50 nm or more and 300 nm or less, wherein the multiwalled carbon nanotubes are homogeneously dispersed between the graphitized carbon nanofibers and near the surface of the graphitized carbon nanofibers. |
