Abstract

The present invention provides a self-ballasted fluorescent lamp L1 which can prevent deterioration of a synthetic-resin globe 6. In the other end side of a cover 2 having a ferrule 1 at one end of the cover 2, a light-emitting tube 4 is arranged and a globe 6 housing the light-emitting tube 4 is attached. The globe 6 is formed with a translucent synthetic resin added to an ultraviolet absorber. A lighting device 5 is housed in the cover 2. The light-emitting tube 4 has a bulb 4d provided with a pair of electrodes 4q, 4r at both ends. An ultraviolet absorbing film 4n is formed on an inner wall surface 4d-1 of the bulb 4d, and a phosphor layer 4m is formed on the ultraviolet absorbing film 4n.
