1. An electrode catalytic layer coated respectively on outer surfaces of an oxidation electrode and a reduction electrode used to generate sterile rater, wherein the electrode catalyst layer is formed on the outer surfaces of the electrodes to have a predetermined thickness, and is composed of iridium (Ir), palladium (Pd), and tantalum (Ta), and
wherein the palladium (Pd) has a weight ratio of 10% to 30%, and a sum of the weight ratios of the iridium (Ir) and the tantalum (Ta) is 70% to 90%.
