PROBLEM TO BE SOLVED: To provide a method for producing saturated gas-containing nano-bubble water, allowing continuous acquisition of constantly stable gaseous saturation nano-bubble water over a long period capable of being used for an electronic industry field such as a semiconductor or a liquid crystal by more stably producing particle-free and metal-free nano-bubble water and controlling a nano-bubble amount.SOLUTION: Pure water is deaerated to generate deaerated pure water, the deaerated pure water is led to a positive electrode chamber and/or a negative electrode chamber of an electrolytic bath electrolyzing pure water to generate gas generation pure water, the current of the electrolytic bath is controlled in a gas generation pure water process, and the pressure of the gas generation pure water having passed through the gas generation pure water process is reduced to generate saturated gas-containing nano-bubble water. |
