PROBLEM TO BE SOLVED: To enhance cleaning effect, up to antibacterial effect, while having deodorization/staining performance not less than that of a fluorescent lamp with a traditional photocatalyst film, without increasing the manufacturing cost. SOLUTION: Oxidized metal fine particles, in which an antibacterial metal of silver or the like is made to be carried, is made to be arranged only in the vicinity of a surface of a comparatively inexpensive titanium film without carrying the antimicrobe metal. As a result of this, the traditional cleaning effect turns into antibacterial effect, and the deodorization performance can be enhanced than that of the conventional cases and the manufacturing cost of the lamp can be nearly the same as that of the conventional cases.
