PROBLEM TO BE SOLVED: To provide a small-sized ozonizer of large capacity having excellent reliability and ozone generation performances. SOLUTION: When fastening tools 11 are gradually fastened and a gas guide 6 is dropped in an arranged state of an electrode substrate 3 and an elastic body 5 on a cooling body 7, the underside of the gas guide 6 is brought into contact with the tips of gap pieces 4 and the gas guide 6 is positioned at a fixed place relatively to the electrode substrate 3 to form a gas channel space 14 of a fixed interval between a dielectric substance 2 and the gas guide 6. At this time, the elastic body 5 arranged between the electrode substrate 3 and the gas guide 6 is pressed by the underside of the gas guide 6 and a pressing force is applied from the side of the gas guide 6 to the electrode substrate 3. In such a state, when a raw material gas 9 is supplied to a gas channel space 14, a high voltage is impressed, through discharge electrode buses 22, between discharge electrodes 1a and 1b to generate a discharge 15, oxygen in the raw material gas 9 is changed into ozone and discharged as an ozonized gas 10.
