Such a carbon fiber having the interlayer distance has a modulus of elongation in the range of not less than 200 GPa and not more than 800 GPa. Particularly the carbon fiber preferably has a volume resistivity in the range of not less than 200μΩ·cm and not more than 2000μΩ·cm. The carbon fiber is preferably a vapor-grown carbon fiber or a graphitized carbon fiber derived from a mesophase pitch as a precursor.
