PROBLEM TO BE SOLVED: To make the thickness of a plane cooler thin without decreasing the cooling capacity and to improve the performance of a discharge cell by constituting the cooler disposed along discharging gap of a cell unit for generating ozone in the discharging gap formed between a pair of electrodes through a dielectric so as to form a cooling medium flow passage between flat metallic plates laminated in the plate thickness direction. SOLUTION: Prescribed high voltage is impressed to a high voltage electrode 32 of the cell unit B while supplying cooling water to a main flow passage C1 to discharge in the discharging gap 34. A gaseous starting material such as gaseous oxygen or the like is supplied to an outside vessel. The gaseous starting material is passed through the discharging gap 34 to generate ozone. The generated ozone gas is recovered in an ozone recovering vessel and discharged to the outside of the outside vessel. The cooling water is passed through the cooling medium flow passage D between each thin plate 22 of the cooler 20 doubled as an earth electrode, extensively cools the discharging electrode 34 from the earth electrode side and is discharged form a maim passage C2 to the outside of the discharge cell A. The thickness of the cooler 20 is controlled to <=0.5-5 mm by combining the flat thin plates 22.
