The electrolytic water generator (100) is provided in a solution tank (110) containing at least a solution containing an electrolyte, a first electrode (112) provided in the solution tank (110), and a first electrode provided in the solution tank (110). A second electrode (113) paired with (112) and at least one amphoteric permeable film (11) provided in the solution tank (110) and located between the first electrode (112) and the second electrode (113). 114) and the first electrode (112) when the second electrode (113) is used as a reference, the first electrode (112) is energized for the first time in the first energization direction, which is the energization direction in which a positive or negative voltage is applied, and the first. A control unit (140) that repeatedly switches the energizing direction in the second energizing direction opposite to the energizing direction so as to energize for a second time different from the first time is provided.
