Abstract
In the present invention, an electrode pair having a discharge space therein is constituted by a combination of a high-voltage application electrode unit and a ground potential electrode unit. The high-voltage application electrode unit has, as the main components, an electrode dielectric film and a metal electrode formed on the upper surface of the electrode dielectric film. An auxiliary conductive film is formed in an annular shape so as to surround the metal electrode without overlapping the metal electrode in plan view. A metal electrode pressing member: has an annular shape in plan view; is provided to contact part of the upper surface of the auxiliary conductive film; and is fixed to a metal base flange. A ground potential is applied to the base flange.
