Abstract
An oxygen generating electrode has a base material with at least a surface thereof made of titanium alone or a titanium alloy, a primary coating formed on the surface of the base material, and a catalyst layer formed on the primary coating and containing an oxide of platinum group element as a main component. The primary coating is composed of a titanium oxide coating and an oxide mixture layer, the titanium oxide coating being made of a titanium oxide only and including a first titanium oxide layer formed by electrolytically oxidizing the surface of the base material and a second titanium oxide layer formed on the first titanium oxide layer by a thermal decomposition method, the oxide mixture layer including at least one layer formed on the titanium oxide coating and consisting of a mixture containing an oxide of an element belonging to a group other than the platinum group, as a main component, and an oxide of a platinum group element.
