(Object> The objects of the invention, in the case of a dielectric barrier discharge lamp, are first to obtain a good space uniformity of the light output, a good time stability of the light output as well as a high light yield, second to achieve a high light coefficient of utilization and at the same time a simple maintenance of the lamp and third not to contaminate a given atmosphere by air or the like. (Arrangement> In a dielectric barrier discharge lamp, in which a discharge vessel, in which a discharge gas forming "excimer" molecules is encapsulated, is provided with a dielectric provided with a netlike electrode and a window, through which the light goes, the first object of the invention is achieved by an arrangement in which a thickness of ends of the above-described netlike electrodes is greater than the average thickness of the entire electrode. The second object of the invention is achieved by an arrangement in which a holder incorporated in the discharge vessel has an outer dimension that is less than/equal to an outer dimension of the netlike electrodes. The third object of the invention is achieved by an arrangement by which the discharge vessel has a hollow cylindrical shape formed from an external tube and an internal tube and a means for hermetic sealing is arranged inside the internal tube.
