Abstract
The carbon fibers of this invention is characterized in that irreducible inorganic material particles in a mean primary particle size below 500 nm and reducible inorganic material particles in a mean primary particle size below 500 nm were mixed by pulverizing and then, the mixture was heat treated under the reducing atmosphere and metal particles in a mean particle size below 1 μm were obtained, and the mixed powder of the thus obtained metal particles with the irreducible inorganic material particles are included in the carbon fibers.
