Abstract

The cold cathode fluorescent lamp has a glass tube in which at least rare gas and mercury gas are sealed into the tightly sealed internal space, and in which a phosphor layer is formed on the inner wall face, a pair of cylindrical electrodes which are arranged in the internal space, in which the base part is formed at one end, and an opening part is formed at the other end, and which is arranged so that the opening parts may be opposed to each other, and a lead wire of which one end is joined to the base part, and of which the other end is drawn out to the outside of the glass tube. The cylindrical electrode is made to have nickel or a nickel alloy as the base material, and formed by a material to which metal having deoxygenation action is added.
