Abstract
A first conductive plate (A) constituting the radiation surface of a slot antenna (A) inclines with respect to a first dielectric member () opposed to the radiation surface of the slot antenna (A). Consequently, a plasma generated by the electric field of an electromagnetic field entering directly from the slot antenna (A) can be set dominant over a plasma generated by the electric field of a standing wave formed in a processing vessel (). Since the former can be controlled more easily than the latter, the plasma distribution can be improved.
