摘要： A method of water electrolysis for producing acidic water and alkaline water is disclosed, which is effective in preventing the dissolution of electrode material in the acidic water, etc. attributable to a reverse current flowing in a power supply cutoff state and also in preventing electrode deactivation caused by the electrode material dissolution. This enables the electrolytic cell to be operated stably over a long period of time to yield high-purity acidic and alkaline waters. An electrolytic cell 1 partitioned into an anode chamber and a cathode chamber with a cation-exchange membrane 2 as a solid electrolyte is used to electrolytically produce acidic water and alkaline water. A voltage of 1.2 V or higher and/or a current of 20 mA/dm.sup.2 or higher is applied between the anode 7 and the cathode 8 when the electrolytic cell is in a power supply cutoff state.
