A cold-cathode fluorescent lamp that realizes high brightness and prolonged durability; and an electrode for this lamp. The electrode is composed of a substratum material and, laid on a surface thereof, a coating layer. The substratum material consists of a member selected from among nickel, a nickel alloy, iron and an iron alloy, so that shapes, such as a cup shape, can be easily formed. The coating layer includes a surface layer of tungsten or molybdenum and, disposed between the substratum material and the surface layer, a junction layer of zinc alloy. The tungsten or molybdenum, as compared with nickel and iron, is difficult in sputtering, is low in work function and has high melting point. By interposing the junction layer, the surface layer and the substratum material can be satisfactorily adhered to each other. The cold-cathode fluorescent lamp equipped with this electrode can reduce drop of brightness, wear of electrode, etc., so that the lamp realizes high brightness and prolonged durability.
