Abstract
In an electric discharge type ozonizer using highly pure oxygen gas having a purity of not lower than 99.99% as a raw material gas, the pressure of a gas in the discharge space of a discharger is raised to a level higher than atmospheric pressure by at least 1.1 kgf/cm.sup.2, and/or in which a liquid-cooled discharger is used, and the temperature of the cooling liquid is set at a level not lower than 15.degree. C., whereby the ozonizer is capable of stably producing ozone gas at a high ozone concentration without causing lowering of the ozone concentration with time.
