PURPOSE: A method for manufacturing an anode for an electrolyzer is provided to prevent passivation and enhance durability of an anode by forming a multilayered structure containing different composition ratios of valve metal. CONSTITUTION: A method for manufacturing an anode for an electrolyzer is as follows. A substrate(1) is coated with an electroconductive base material, thereby manufacturing an anode. The basic mol composition of the coating material is AxByCz, where x+y+z=100, A and B are PGM(Platinum Group Metals), and C is valve metal. Coating layers(2,3,4) are formed on the substrate, where the coating layer contacting the substrate contains the largest amount of valve metal while the content of valve metal in a coating layer decreases in proportion to the distance from the substrate. The composition ratio of valve metal is changed according to the content of oxygen.
