PROBLEM TO BE SOLVED: To provide a cold cathode fluorescent lamp and an illumination device that have high luminance maintenance factor and long life and contribute to performance improvement of OA equipment and liquid crystal devices. SOLUTION: This is a cold cathode fluorescent lamp 11 that comprises a glass tube 1 on the inner wall of which a phosphor layer 2 is provided and mercury and rare gas are filled as a discharge media, a lead wire 3 that is sealed and introduced opposed to each other at both ends in the glass tube 1 and is connected to a lead wire for outside feeding, and a discharge electrode 4 that is respectively electrically connected to the facing top end of the lead wire 3. A metal oxide layer 5 having high affinity to mercury is coated on the phosphor layer 2 in the region excluding the main irradiation face 6 of the above cold cathode fluorescent lamp 11.
