In the excimer lamp according to the present invention, a flat discharge vessel having a substantially rectangular cross-sectional shape and comprising a pair of planar parts and a pair of side-surface parts has a pair of external electrodes disposed on the respective outer surfaces of the planar parts. The end parts of the external electrodes are provided with an auxiliary electrode extending to a region that is made smaller than the distance between the planar parts. A lead that supplies electricity to the external electrode is connected to the auxiliary electrode in the region that is made smaller than the distance between the planar parts.

A double-ended high intensity discharge lamp includes a luminous tube which comprises an inner tube and an outer tube. At least one electrical member is securely fastened inside the luminous tube and at least one illuminator supported inside the luminous tube with a distributor connected with the electrical member to receive power and supply the illuminator. The outer tube is another protective shield to stop spreading in explosion of the illuminator.
