PROBLEM TO BE SOLVED: To produce highly oxidative water containing ozone and the like in excellent electrical efficiency with high productivity by dissolving an oxygen- rich gas in water under high pressure, then lowering the pressure to generate microfine bubbles of the oxygen-rich gas and exposing the microfine bubbles to the pulsed electric discharge. SOLUTION: Water is introduced into a high-pressure tank, an oxygen-rich gas is blown from a high-pressure bomb 6 through an aerator 7 into the water in microfine bubbles so that the oxygen-rich gas is dissolved in the water. At this time, the pressure in the high-pressure tank is measured with a pressure gauge 5 to adjust the pressure to several to several tens atmospheric pressure. The water saturated with oxygen-rich gas is transferred to the low-pressure tank 2, the pressure-reducing valve 9 is opened to reduce the pressure in the low-pressure tank. At this time, the oxygen-rich gas dissolved in the water is supersaturated with the oxygen-rich gas to generate microfine bubbles wholly in the water. High-voltage pulses are applied from the pulse power supply to the electrode 3 to generate ozone whereby the objective high-oxidative water including high concentrations of ozone and/or OH radical is obtained.
