Provided is a sterilizing-water generation device which is characterized by being provided with: a hypochlorous acid-containing water generation unit which electrolyzes tap water to generate hypochlorous acid-containing water; a bactericidal-metal-ion water generation unit provided with electrodes which electrolyze tap water to elute bactericidal metal ions into the tap water; a water discharge unit which discharges the hypochlorous acid-containing water and/or the water including the bactericidal metal ions; and a control unit which controls operation of the hypochlorous acid-containing water generation unit and the bactericidal-metal-ion water generation unit. The sterilizing-water generation device is further characterized in that, in cases when the concentration of the hypochlorous acid in the hypochlorous acid-containing water is relatively low, the concentration of the bactericidal metal ions in the water including the bactericidal metal ions is relatively high.
