摘要： An ozone generator includes one or more electrode pairs each containing two electrodes arranged at a distance of a predetermined gap length and a power source for applying an alternating-current voltage between the two electrodes. In the ozone generator, ozone is produced when a source gas flows at least between the two electrodes and a discharge is generated between the two electrodes. The ozone generator has a discharge space formed between the two electrodes, and the ozone generator satisfies the condition of 0.5
