PROBLEM TO BE SOLVED: To surely clean electrodes without increasing the cost by judging the state of the electrolytic water remaining between the electrodes based on the detected value of the residual voltage generated between the electrodes while the electrolysis voltage after electrolysis is turned off. SOLUTION: In the electrolytic water generator, when a signal is received from an electrolytic switch or a user detection sensor, a solenoid valve SV1 is opened to start a brine pump 3, city water and A brine stored in a brine tank 2 are supplied to a mixing part 4, the brine is supplied to an electrolytic cell 6 through a filter 5, and electrolysis is conducted. An acidic water contg. hypochlorous acid is discharged and an alkaline water exhausted by a passage switching valve 7. The brine pump and electrolytic cell are turned on or off by a controller 8 based on a signal from a flow sensor 1. The residual voltage generated between the electrodes when the electrolysis is stopped and water supplied is detected, and the water supplying time when electrolysis is stopped is determined from the residual voltage. Consequently, the remaining electrolytic water is surely discharged without increasing the cost.
