PROBLEM TO BE SOLVED: To provide a long life flat fluorescent lamp for giving a homogeneous flat light without generation of noise. SOLUTION: A transparent electrode 24 and a flat electrode 25 are formed on the inner surface of a glass plate 11 and 12. A spacer glass 13 connects the transparent electrode 24 and the flat electrode 25 with a space to form a sealed container 15. A fluorescent film 18 is disposed on the inner surface of the transparent electrode 24. A circumferential conductive wire 31 is disposed on the outer edge of a projection from the glass spacer 13 of the transparent electrode 24. A discharge and light emission are performed by connecting a sine wave power source 34 between the electrode 25 and the circumferential conductive wire 31. A dielectric material film 35 is disposed on the inner surface of the electrode 25. A sealing gas is sealed in the space formed in the sealed container. The partial pressure of the discharge gas is set about 10 torr. COPYRIGHT: (C)2007,JPO&INPIT
