PROBLEM TO BE SOLVED: To obtain an ozone generating element capable of stably supplying ozone over a long period by eliminating mismatching discharge caused by electric focusing. SOLUTION: In this ozone generating element for generating ozone by creeping discharge by providing a dielectric body 3 between a discharge electrode 1 connected to a high-frequency high voltage power source and an earth electrode 2, the max. surface roughness (RMAX) of the side surface of the discharge electrode 1 is controlled to <=3μm.
