PROBLEM TO BE SOLVED: To provide a sterilized water generator capable of simultaneously realizing, at high levels, goals of miniaturizing the sterilized water generator, of improving the sterilized water generating capacity, and of extending the electrode life.SOLUTION: In a sterilized water generator for generating hypochlorite-sterilized water by directly electrolyzing water including chloride ions so as to generate chlorine on an anode and then reacting the chlorine with water, an electrode obtained by configuring a catalyst layer atop an electrode substrate consisting of titanium or titanium alloy and configured within an electrolytic tank through which the water including chloride ions is scheduled to be transported and a control means for generating a hypochlorite within the electrolytic tank by permeating a current through the electrode are furnished, whereas the control means is constituted to permeate a current through the electrode at a current density of 7 A/dmto 20 A/dmand to execute a pole change of switching the anode and cathode of the electrode, whereas the catalyst layer of the electrode is constituted as a composite of a metal and/or metal oxide including at least iridium oxide, rhodium oxide, and tantalum oxide, whereas the platinum element concentration within the composite is below 4 mol%. |
