Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the following problems: in the conventional water softener uses salt for regenerating a cation exchange resin, periodic salt replenishment is necessary according to the amount of used soft water and the salt replenishment requires a lot of time and labor. SOLUTION: In a water softener, an anode chamber filled with a cation exchanger and a cathode chamber filled with an anion exchanger are formed by separation with a diaphragm, and the anode and cathode chambers are each provided with an electrode. When the cation and anion exchangers are regenerated, an voltage is applied across the electrodes to generate hydrogen ions and hydroxide ions, and the hydrogen ions and hydroxide ions regenerates the cation and anion exchangers, which dispenses with supply of a chemical and enables continuously obtaining soft water.
