Abstract
Provided are an anode for alkaline water electrolysis that can achieve a low overpotential at low cost, and a method for producing the anode for alkaline water electrolysis. An anode for alkaline water electrolysis having electrode catalyst layers 2, 3 composed of a first catalyst component having either a nickel-cobalt spinel oxide or a lanthanide-nickel-cobalt perovskite oxide and a second catalyst component having at least one of iridium oxide and ruthenium oxide formed on the surface of a conductive substrate 1 composed of nickel or a nickel-based alloy, and a method for producing the anode for alkaline water electrolysis.
