<p>The amount of ozone generated is not reduced while reducing the radiation of high-frequency noise from connection lines by preventing a high-frequency current generated in discharge electrodes from flowing into the connection lines and while reducing the effect of an applied voltage by preventing the high-frequency current from flowing into the connection lines. In an ozone generating device (4) for applying a high voltage from a drive circuit to discharge electrodes (41) to generate ozone by the silent discharge of the discharge electrodes (41), inductances (43) are provided to connection terminals (44) of the discharge electrodes (41) to obtain the ozone generating device (4) in which the connection lines extending from the drive circuit are connected to the discharge electrodes (41) through the inductances (43).</p>
