An electrode assembly for use in a dielectric barrier discharge plasma source comprises a base metal plate, an enamel layer on a surface of the base metal plate and embedded electrodes embedded in the enamel layer. The electrode assembly may be made by depositing a one or more layers of powdered glass over a surface of the base metal plate, fusing the powdered glass the one or more layers each in a separate heating step for the relevant layer. To form the embedded electrodes, a pattern of electrode material is provided over the powdered glass of the one or more layers after fusing the one or more layers. Subsequently one or more further layers of powdered glass are deposited over the electrodes and the layer(s) below it, and the powdered glass in each of the one or more further layers is fused in a separate heating step.
