Disclosed herein is a plasma generating apparatus capable of sufficiently performing a deodorization function and a sterilization function by increasing a generation amount of ions or radicals while suppressing generation of ozone. The plasma generating apparatus has a pair of electrodes (and) provided with dielectric films (and) and serves to apply a predetermined voltage between the electrodes (and) to discharge plasma, fluid circulation holes (and) are respectively provided at corresponding positions of the respective electrodes (and) and pass through the electrodes, and plasma is generated only in opening end portions (and) forming the fluid circulation holes (and) between the pair of electrodes (and).

Plasma generating apparatus

Generated amount of active species is increased, and dew formation or moisture attachment hardly occurs on a dielectric layer. A plasma generating apparatus including a pair of electrodes, wherein a dielectric layer is arranged on at least one of surfaces of the electrodes facing each other, plasma discharge occurs as a predetermined voltage is applied to the electrodes, and a coating film is arranged on a surface of the dielectric layer.

Plasma generating apparatus and plasma generating method

The purpose of the present invention is to minimize ozone production while increasing the production of an active species. The plasma generating device () comprises: a pair of electrodes () in which dielectric films () are disposed on at least one opposing face; voltage application means () for applying a pulse voltage across the electrodes () to bring about a plasma discharger; and fluid circulation holes () that are disposed in locations corresponding to the electrodes (), respectively, and that are configured to pass entirely therethrough. The plasma generating device is also configured such that a fluid passing through the fluid circulation holes () comes into contact with the plasma, generating ions or radicals, wherein the voltage applying means () varies the peak value and/or the pulse width of the pulse voltage applied across the electrodes ().
