To provide an anode for electrolysis that shows a lower concentration of by-product oxygen gas in chlorine gas and shows a lower overvoltage stably for a long period of time than conventional anodes, and a manufacturing method therefor.

The anode for electrolysis include a substrate comprising titanium or titanium alloy and a coating layer made up of a plurality of unit layers laminated on the surface of the substrate, the unit layers comprising a first coating layer made up of a mixture of iridium oxide, ruthenium oxide and titanium oxide, and a second coating layer made up of a mixture of platinum and iridium oxide. The manufacturing method therefor includes the following. In the coating layer made up of a plurality of the unit layers laminated on the surface of the substrate, the first coating layer is brought in contact with the surface of the substrate, and the second coating layer is formed on the outermost layer. After the coating layer made up of a plurality of the unit layers is provided on the surface of the substrate by a thermal decomposition baking method, the coating layer is post-baked at a temperature higher than the baking temperature by the thermal decomposition baking method.
