Abstract: An anode for oxygen generation and a manufacturing method for the same used for industrial electrolyses including manufacturing of electrolytic metal foils such as electrolytic copper foil, aluminum liquid contact and continuously electrogalvanized steel plate, and metal extraction is provided. The anode for oxygen generation and a manufacturing method for the same comprises a conductive metal substrate and a catalyst layer containing iridium oxide formed on the conductive metal substrate wherein the coating is baked in a high temperature region of 410° C.-450° C. in an oxidation atmosphere to form the catalyst layer co-existing amorphous and crystalline iridium oxide and the catalyst layer co-existing the amorphous and crystalline iridium oxide is post-baked in a further high temperature region of 520° C.-560° C. in an oxidation atmosphere to crystallize almost all amount of iridium oxide in the catalyst layer.
