Described is a ozonizer (10) with a first metal electrode (14) and a second metal electrode (20) with a discharge gap (18) between them, the first electrode (14) being covered with a dielectric (16). At least the first electrode (14) is designed as an aluminium or aluminium-alloy coating on a glass substrate. The dielectric (16) consists of a thermally sprayed ceramic film, preferably made of alpha -aluminium oxide, titanium oxide or hafnium oxide. Also described is a method of manufacturing the ozonizer, the method calling for the ceramic film acting as the dielectric (16) on the first electrode (14) to be applied by thermal spraying. The two electrodes (14, 20) are preferably also produced by thermal spraying. The ozonizer has a particularly high yield, is corrosion-resistant and can be manufactured simply and inexpensively.
