ABSTRACT:
An electrolytic electrode having an interlayer having more excellent peeling resistance and corrosion resistance and longer electrolytic life than conventional electrolytic electrodes and capable of flowing a large amount of current at the industrial level and a process of producing the same are provided. The electrolytic electrode includes a valve metal or valve metal alloy electrode substrate on the surface of which is formed a high-temperature oxidation film by oxidation, and which is coated with an electrode catalyst. The high-temperature oxidation film is integrated with the electrode substrate, whereby peeling resistance is enhanced. Further, by heating the high-temperature oxidation film together with the electrode catalyst, non-electron conductivity of the interlayer is modified, thereby making it possible to flow a large amount of current.
