    Abstract: A plasma probe device includes an antenna unit installed at an opening formed in a wall of a processing chamber or a mounting table through a sealing member configured to seal between a vacuum space and an atmospheric space, an electrode connected to the antenna unit, and a dielectric support portion made of a dielectric material and configured to support the antenna unit from an outer peripheral side. A surface of the antenna unit which is exposed through the opening and separated from a facing surface of the wall or the mounting table facing the antenna unit by a width is depressed from a surface of the wall or the mounting table where the opening is formed, which faces a plasma generation space.
