PROBLEM TO BE SOLVED: To obtain an electroconductive antioxidative coating material having an excellent antioxidative effect at a high temperature of >=1,800 deg.C. SOLUTION: This electroconductive antioxidative coating material is characterized in that the coating material comprises an electroconductive material, an antioxidizing material, a polymer emulsion as a binder, an inorganic colloid and a transition metal in an aqueous medium and the content of the alkali metal and/or an alkaline earth metal is <=20 wt.% based on the amount of the antioxidant. The antioxidizing material is a carbide or a nitride of a simple substance selected from the group consisting of B, Si, Ge, Sb, Ti, Sn, Al and Zr or a simple substance of B or Si.
