置。6. An electrolytic cell having an electrode plate facing inside and having no diaphragm, means for passing raw water through the electrolytic cell, and direct current supplied to the raw water in the electrolytic cell by each of the electrode plates. Means for applying a voltage to flow a direct current, means for switching the polarity of the DC voltage applied to each of the electrode plates, and means for adding salt water to the raw water in the electrolytic cell from each of the water passages formed on each of the electrode plates. Means for switching the salt water to be supplied to each of the water passages, and means for laminating the flow of the raw water in the electrolytic cell when the water flows, and synchronizes the switching operation of the polarity switching means and the salt water switching means. An electrolyzed water generator characterized by the following.
