ABSTRACT:
A fluorescent lamp has a translucent container and a phosphor layer formed on an inner surface of the translucent container, and the phosphor layer comprises phosphor particles and a metal oxide that is arranged to adhere to any of contact portions among the phosphor particles and to partially expose surfaces of the phosphor particles. According to the present invention, film strength of the phosphor layer is improved while suppressing a drastic drop in an initial flux of the fluorescent lamp and deterioration of the luminance.
