Claim 0:
1. A carbide-coated carbon material comprising:
a base material containing carbon as a main component and chlorine; and
a carbide layer containing a carbide as a main component and chlorine, the carbide layer being disposed on the base material, wherein
the base material has, near an interface between the base material and the carbide layer, a base material buffer region where a chlorine concentration continuously changes in a direction toward the carbide layer,
the carbide layer has, near the interface between the base material and the carbide layer, a carbide layer buffer region where the chlorine concentration continuously changes in a direction toward the base material, and
the maximum values of chlorine concentrations at the base material buffer region and the carbide layer buffer region are 10,000 ppm or less.
