Abstract: This invention relates to an electrolytic ion water generator for producing alkali ion water containing alkali ions and acid ion water containing acid ions by introducing tap water or the like into an electrolytic cell comprising electrodes and ion exchange membranes arranged alternately which electrolyze the electrolytes in the water.Electrolytic cell unit panels having the same shape are constructed by attaching the electrode plate and ion exchange membrane onto each synthetic resin frame. The electrolytic cell unit panels are layered in a water-tight manner facing the front sides to front sides and the rear sides to rear sides via O-rings. A water-inlet external cover is attached at one end of the layered electrolytic cell unit panels, and a water-outlet external cover is attached at the other end of the layered electrolytic cell unit panels in a water-tight manner to secure the total assembly.
