Abstract:
1. A discharge device generating discharge phenomena, comprising: a single insulating dielectric body; a discharge electrode having an electrode forming part of a predetermined area on a surface of the insulating dielectric body and at least one non-electrode forming part disposed in the electrode forming part; and a ground electrode formed at an opposite surface of the insulating dielectric body to the surface at which the discharge electrode is formed, wherein the discharge electrode and the ground electrode have a plurality of pointed ends protruded therefrom, respectively, such that the pointed ends of the discharge electrode and the pointed ends of the ground electrode are protruded in an opposite direction to each other, a protective film is coated on each of an upper surface and a lower surface of the insulating dielectric body to protect the discharge electrode and the ground electrode, the electrode forming part is a pattern part of a predetermined area formed on the upper surface of the single insulating dielectric body, and the non-electrode forming part is a non-pattern part disposed in the pattern part, and the ground electrode extends a predetermined length in the longitudinal direction at a place on which the non-pattern part of the discharge electrode is reflected when the discharge electrode is projected in the perpendicular direction to the surface of the single insulating dielectric body at which the ground electrode is formed.
