Abstract:
A fluorescent lamp according to the present invention includes: a glass tube 1 in which mercury and a rare gas are enclosed; a protective film 3 that is attached so as to cover an inner face of the glass tube 1; and a phosphor layer 4 that is laminated on the protective film 3. The protective film 3 has a thickness of 0.5 μm to 3 μm. Further, the protective film 3 is formed of inorganic particles and has a volume ratio of 0.1 to 0.5. Preferably, the inorganic particles are of at least one selected from the group consisting of aluminum oxide, silicon dioxide, magnesium oxide, zinc oxide, titanium oxide, cerium oxide, yttrium oxide, and calcium halophosphate.
