(57) [Summary] [PROBLEMS] To efficiently generate hypochlorite ion which is a sterilizing component. SOLUTION: A cation exchange membrane 20 is provided inside an electrolytic cell 8. A pair of electrodes 18 and 19 are arranged separated by. When the water purification device 1 starts the bath water purification operation, when a voltage is applied between the electrode 18 and the electrode 19, the electrode 18 (negative electrode side) In the electrolytic chamber 21 in which is disposed, hydroxide ions and chloride ions react with each other to generate hypochlorite ions, which are sterilizing components. The hydroxide ion and the chlorine ion existing in the electrolytic chamber 21 are separated from the electrolytic chamber 22 in which the electrode 19 (the positive electrode side) is disposed. And cannot be decomposed into oxygen gas and hydrogen gas, respectively. Therefore, hypochlorite ions can be efficiently generated. |
