A plasma nozzle for treating surfaces, especially for the pre-treatment of plastic surfaces, with a tubular, electrically conductive housing (10), which forms a nozzle channel (12), through which the working gas is flowing, an electrode (18), disposed coaxially in the nozzle channel, and a high-frequency generator (20) for applying a voltage between the electrode (18) and the housing, wherein the outlet of the nozzle channel (12) is constructed as a narrow slot (32), which extends transversely to the longitudinal axis of the nozzle channel.
