PROBLEM TO BE SOLVED: To provide an electrode for water treatment, which has a great oxidative function as an anode, further can be used as a cathode, and has an electric potential suitable for decomposing organic matters and sterilizing microorganisms. SOLUTION: The electrode for water treatment includes a coating layer of a catalyst, which mainly contains tantalum oxide and further contains a platinum group metal. The tantalum oxide exists in the electrode, thereby the overvoltage of the platinum group metal moves to the electric potential suitable for decomposing the organic matters and sterilizing the microorganisms. Thus provided electrode suits for electrolytically treating wastewater containing the organic matters and having a high COD, while keeping a strong electrolytically oxidizing function and adequate corrosion resistance.
