Abstract
A conductive diamond electrode including an electrode substrate comprising a material selected from the group consisting of a valve metal and an alloy based on the valve metal, at least a surface of the metal or alloy having been subjected to plasticization processing, or heat treatment in vacuum or inert atmosphere; and a conductive diamond film formed on the plasticization processed surface of the electrode substrate. When the electrode substrate is subjected to plasticization processing and heat treatment, peeling resistance of the conductive diamond film is improved, thereby an electrode life is prolonged.
