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.
