Provided is a production method for electrodes for electrolysis, whereby the amount of an electrode catalyst component can be suitably adjusted to a desired amount, and high-performance electrodes for electrolysis can be economically and efficiently produced without losing electrode performance. The production method for electrodes for electrolysis has a step in which a coating fluid containing an electrode catalyst component starting material is coated on the surface side of a conductive electrode base material having a plurality of pores, such as an expanded mesh, etc., said material is subsequently dried and fired, and an electrode catalyst layer is formed on the surface side and rear side of the base material. In said production method, the base material contains at least one type of metal selected from Ti, Ta, Nb, Zr, Hf, and Ni, or an alloy thereof; the electrode catalyst component contains at least one selected from Pt, Ir, Ru, Pd, Os, and oxides thereof; and the amount of electrode catalyst component attached to the rear side of the base material is adjusted by pre-heating the base material at least once in the electrode catalyst layer formation steps, increasing the temperature of the base material to higher than room temperature immediately prior to applying the coating fluid, and then again changing the temperature thereof.
