PROBLEM TO BE SOLVED: To provide a dielectric barrier discharge lamp for improving cooling efficiency of a discharge container of a discharge tube by a comparatively simple constitution. SOLUTION: In an external electrode 1 or an internal electrode 3 of the discharge container 2 of a hollow coaxial duplex structure, many projected heat radiating plates 12 and 32 are integrally or separately formed. By increasing contact area with fluid for cooling, cooling efficiency of the dielectric barrier discharge lamp is improved.
