Abstract

A fluorescent lamp and a process for the production thereof are provided whereby the consumption of mercury is prevented, sealed-in mercury is drastically reduced, and the lamp has high retention of luminous flux and achieves an expanded lifespan. The fluorescent lamp includes an arc tube and a protective layer on an inner surface of the arc tube, the protective layer including connected particles having a volume-average particle diameter of 10 to 300 nm, the connected particles being composed of an oxide of a metal not forming an amalgam with mercury. The fluorescent lamp includes: an arc tube; and on an inner surface of the arc tube and in the order named: at least one of a UV absorbing layer and a UV reflecting layer; a protective layer including connected particles having a volume-average particle diameter of 10 to 300 nm, the connected particles being composed of an oxide of a metal not forming an amalgam with mercury; and a fluorescent layer.
