Abstract
A discharge light having a light emitting tube () encapsulates a discharging medium, an inner electrode () disposed in the light emitting tube, and an outer electrode unit () fixed to the outside of the light emitting tube. The outer electrode unit has at least a plurality of outer electrodes () arranged intermittently in the axial direction of the tube and having a part abutting on the outer wall face of the light emitting tube, and a part () engaging with the light emitting tube while coupling the outer electrodes thereof integrally, wherein the engaging part clamps the light emitting tube at a part thereof thus holding the outer electrode unit around the light emitting tube. The light emitting tube is lighted by applying a voltage between the inner electrode and the outer electrode. The outer electrode can be fixed readily to the light emitting tube and the plurality of outer electrodes can be held against the light emitting tube with high accuracy.
