Abstract

An electrode arrangement for forming a dielectric barrier plasma discharge between a flat surface (4) of the electrode arrangement and a surface to be treated which functions as a counter surface and on which a fluid can collect, comprising a flat electrode (14) which can be connected to a high-voltage source by means of a connector and which is completely embedded in a flat dielectric (2), except for the connector for the high-voltage source, wherein the dielectric (2) forms an upper surface (1) and a lower surface (4) which appears as a flat surface to the surface to be treated, enables the drainage or supply of a fluid by means of a simple design. The flat electrode (14) has through openings (15) distributed across the surface thereof, and the dielectric (2) is provided with through openings (3) which extend from the lower surface (4) to the upper surface (1) and which align with the through openings (15) of the electrode (14) and which have smaller dimensions than the through openings (15) of the electrode (14), so that the dielectric (2) is also completely covered in the region of the through openings (15) of the electrode (14).
