Stage: PROBLEM TO BE SOLVED: To provide an electrode catalyst that is less likely to cause an increase in overvoltage during water electrolysis and can stably operate for an extended period of time even at high current densities, and also to provide an oxygen generating electrode equipped with the electrode catalyst and a water electrolysis method.SOLUTION: An electrode catalyst according to the present invention is an electrode catalyst with a catalyst on an electrode substrate, the catalyst containing a sulfide that contains nickel and iron as constituent elements. An oxygen generating electrode according to the present invention includes the electrode catalyst. A water electrolysis method according to the present invention includes a step of using the oxygen generating electrode to electrolyze water. The electrode catalyst according to the present invention, when used as an electrode for water electrolysis, is less likely to cause an increase in overvoltage during water electrolysis and can stably operate for an extended period of time even at high current densities.SELECTED DRAWING: None (Grant)
