PROBLEM TO BE SOLVED: To solve the problem that a diamond film on the peeling-off and the wear of a diamond electrode occur by the causes that diamond has thermal expansion coefficient remarkably smaller than that of a substrate to leave excessive thermal stress remains on the diamond film, the sure adhesion of the film to the substrate is hardly attained, a good quality film is not applied homogeneously on a large-scaled electrode or the like though the diammond electrode coated with the conductive diamond film is expected to be applied on wide fields such as a water treatment because of the wide electrochemical potential window. SOLUTION: In the method of manufacturing the electrode, after being applied on the substrate by a low pressure vapor phase synthesis, the diamond film is once separated from the substrate and is applied on another substrate with a conductive adhesive. As a result, thermal stress is removed, the most suitable material for the substrate and an electrode plate is individually selected, the high quality and homogeneous film is applied even on a large surface area and then, the adhesion of the diamond film is firm and sure to reduce the peeling-off or the wear. Further, because a small surface area of a diamond film can be applied by the method, expensive manufacturing equipment is needless even in the case of producing a large electrode.
