<;P>;PROBLEM TO BE SOLVED: To provide an electrolytic water generator which is excellent in maintainability and is capable of preventing clogging of a filter due to the deposition of scale, and a sterilization system provided with the electrolytic water generator. <;P>;SOLUTION: The electrolytic water generator includes: a water storage tank 51; an electrolysis unit 52 for electrolyzing water inside the water storage tank 51 and generating electrolytic water containing active oxygen species; and an electrolytic water supply pump for supplying the electrolytic water to the air sterilization part of the water storage tank 51. The water storage tank 51 is sectioned into a first chamber 90A provided with the electrolysis unit 52 and a second chamber 93 communicated with the electrolytic water supply pump, and includes a scale filter 96 for catching the scale in the electrolytic water flowing from the first chamber 90A to the second chamber 93, and a water supply nozzle 86A for supplying the water from a filter upper surface 96B on the opposite side of a filter lower surface 96A to be the catching surface of the scale filter 96 toward the scale filter 96 when supplying the water to the water storage part 51. <;P>;COPYRIGHT: (C)2011,JPO&INPIT
