Abstract
Provided is an electrode for electrolysis with excellent corrosion resistance and durability which can be used sustainably in the production of a high-purity quaternary ammonium hydroxide by the electrolysis of a quaternary ammonium inorganic acid salt in an electrolytic cell partitioned by a cation exchange membrane on a commercial scale with reduced electric power consumption at low cost. The electrode for electrolysis is useful for the production of a quaternary ammonium hydroxide by the electrolysis of a quaternary ammonium inorganic acid salt in an electrolytic cell partitioned by a cation exchange membrane and comprises an electrode base material of an electrically conductive metal, an electrode active layer containing an electrode active material covering the electrode base material, and an intermediate layer of a mixed oxide of an oxide of at least one kind of metal selected from In, Ir, Ta, Ti, Ru, and Nb and an oxide of Sn disposed between the electrode base material and the electrode active layer.
