Abstract

Disclosed is a carbon material, such as a carbon nanotube, into which a boron atom and/or a phosphorus atom is/are introduced while maintaining its characteristic structures and functions and a method for producing the same. The carbon material of the present invention is one in which a boron atom and/or a phosphorus atom is/are introduced into part of carbon atoms composing the carbon material, and can be produced by a method for producing a carbon material including the steps of: bringing a carbon material into contact with a fluorination treatment gas containing a fluorine-containing gas, thereby subjecting a surface of the carbon material to fluorination treatment; and bringing the carbon material after the fluorination treatment into contact with a boronization treatment gas containing a boron-containing gas, thereby subjecting to boronization treatment and/or into contact with a phosphorization treatment gas containing a phosphorus-containing gas, thereby subjecting to phosphorization treatment.
