Abstract
A highly electroconductive graphite continuous filament is described, which is composed of a carbon filament as a substrate and a graphite layer having a layer spacing d (0,0,2) of not larger than 3.363 angstroms as an outer skin layer The graphite continuous filament is prepared by depositing easily graphitizable carbon on the substrate and heat-treating the carbon-deposited substrate at a temperature of at least 2,500.degree. C.
