In order to provide an electrolysis electrode that is able to maintain superior catalytic activity in a stable manner over a long period of time without a deterioration in electrolytic performance, even when power such as renewable energy for which there is a large fluctuation in the output is used as the power source, an electrolysis electrode 10 comprises: a conductive substrate 2 at least the surface of which comprises nickel or a nickel-based alloy; an intermediate layer 4 formed on the surface of the conductive substrate 2 and comprising a lithium-containing nickel oxide represented by the composition formula LixNi2-xO2 (0.02≤x≤0.5); and a catalyst layer 6 of a nickel cobalt spinel oxide, iridium oxide, or the like formed on the surface of the intermediate layer 4. |
