Plasma generating apparatus

In order to provide a plasma generating device which is both very safe and has excellent bactericidal properties and deodorizing properties, this plasma generating device, which is provided with a pair of electrodes having a dielectric film formed on at least one of the facing surfaces thereof, and which is for discharging plasma when a prescribed voltage is applied between the electrodes, is configured such that the dielectric constant of the dielectric film is 20-200.
