PROBLEM TO BE SOLVED: To provide a plane rare gas fluorescent lamp that may enhance the brightness of the central portion. SOLUTION: A translucent flat first member 1 is combined with a second member 2 comprising a plurality of wall faces 4 connected in parallel with a connector 5 interposed between the adjacent wall faces, each of which forms a channel-like space 3 having a light-emitting layer 8 formed on its inside surface. The first and second members 1 and 2 have the peripheries sealed to contain a rare gas in the space formed between them. The external electrodes 9 and 10 are separately attached to both sides of each wall face 4 along the extended direction of the channel-like space 3. The cross section of the channel- like space 3 may be shaped semicircular, oval, arched, sine-wave-like, etc.
