Abstract

The present invention provides a method for manufacturing an electrolytic electrode, the method capable of appropriately controlling the amount of an electrode catalyst component as desired and also capable of manufacturing a high-performance electrolytic electrode in a cost-effective and efficient way without affecting the electrode performance. A method for manufacturing an electrolytic electrode including a step of forming an electrode catalyst layer on each of a front and a back of a conductive electrode substrate, by applying a coating solution containing a starting material for the electrode catalyst component on the front of the conductive electrode substrate with a plurality of holes, the conductive electrode substrate being expanded mesh or the like, and thereafter drying and firing the coating solution, wherein the substrate contains at least one metal selected from the group consisting of Ti, Ta, Nb, Zr, Hf, and Ni, and alloys thereof, the electrode catalyst component contains at least one selected from the group consisting of Pt, Ir, Ru, Pd, Os, and oxides thereof, and an amount of the electrode catalyst component adhering to the back of the substrate is controlled by preheating the substrate to a temperature higher than room temperature at least once before the coating solution is applied and/or by presetting the temperature to which the substrate is preheated in the electrode catalyst layer-forming step.
