PROBLEM TO BE SOLVED: To provide an electrode having no problem of deterioration or exfoliation and capable of stably performing electrolysis wherein high voltage and large electric current is applied, an ozone generator using the electrode and a method to produce ozone. SOLUTION: An anode 3 and a cathode 5, interposing a solid polymer film 7, are disposed. While supplying purified water from a supply port 13a of an anode chamber 13, wherein the anode 3 is disposed, and a supply port 15a of a cathode chamber 15, wherein the cathode 5 is disposed, direct electric current is applied between the anode 3 and the cathode 5. As a result, ozone-water is discharged from an outlet port 13b of the anode chamber 13. In such an electrolysis cell 1, a free-standing conductive diamond plate, formed by microwave plasma assisted CVD so as to have a thickness of 0.8 mm, is used as the anode 3. The diamond plate is provided with holes, having a diameter of 1 mm and disposed such that a center distance therebetween becomes 2 mm. Therefore, the electrolysis cell 1 can stably produce ozone without causing exfoliation of the anode 3, even when high voltage and large current are applied between the anode 3 and the cathode 5.
