ABSTRACT:
An electrolytic electrode substrate comprises an electrically conductive substrate and, formed on the surface of the electrically conductive substrate, an oxide layer having a thickness of from 10 to 200 .mu.m, wherein the oxide in the oxide layer comprises a non-stoichiometric composition containing oxygen and at least one metal selected from the group consisting of titanium, tantalum, and niobium. An advantage of the electrode substrate is that it is stable when used in electrolytic processes involving a reversal of current flow. Further, the electrode substrate is stable in the presence of corrosive substances such as a fluorine.
