description A device (1) for plasma treatment comprises an electrode (2) having a surface (14) covered by a dielectric barrier (3), and an AC high voltage source (6) for applying an AC high voltage to the electrode (2) to bring about a dielectric barrier discharge (9) in a gas (10) at atmospheric pressure present in front of the dielectric barrier (3) in order to generate a plasma. To the end of generating the plasma even without a counter-electrode for the electrode (2), pointed tips are distributed over the surface (14) of the electrode (2), these pointed tips pointing towards the gas (10) in front of the dielectric barrier (3), whereas the dielectric barrier (3) has a smooth outer surface (15) facing the gas (10).
