PROBLEM TO BE SOLVED: To provide a rare gas fluorescent lamp enabled to have a distribution of luminance in a tube axis direction of a luminous tube, without raising an input power. SOLUTION: The rare gas fluorescent lamp is provided with a phosphor layer 2 over a whole inner face of the straight-tube luminous tube 1 with rare gas sealed in and a pair of strip-shaped outer electrodes 3 extended in a tube axis direction at an outside face of the luminous tube 1. A conductor 4, provided at an outer face of the luminous tube 1 not electrically connected with the outer electrode 3, is formed extended toward the tube axis direction separated from and in parallel with the outer electrode 3. Further, the conductor 4 is formed at a center part in a tube axis direction of the luminous tube 1. COPYRIGHT: (C)2009,JPO&INPIT
