PROBLEM TO BE SOLVED: To provide a sterilization water discharge device that can properly discharge a sterilization water at the timing when the user requires the same without requiring the replenishment of chemicals or the like from the outside as well as while being almost free from maintenance.SOLUTION: The sterilization water discharge device is configured such that, during the time of discharging a sterilization water, a dirt-off process for discharging a water on which an electrolysis in an electrolysis tank 600 is not conducted, for the purpose of washing off the dirt, and a sterilization process for discharging a sterilization water that is produced by conducting an electrolysis in an electrolysis tank 600, for the purpose of sterilizing, are executed in sequence the applied voltage on an electrode 510 within a concentration tank 500 is controlled such that an adsorption treatment is executed during the dirt-off process and a desorption treatment is executed during the sterilization process and the applied voltage on the electrode 510 within the concentration tank 500 is controlled such that an adsorption treatment is executed even during the discharge of a water on which an electrolysis in the electrolysis tank 600 is not conducted, from a main spout 100.
