PROBLEM TO BE SOLVED: To provide an electrode alloy for fluorescent discharge tube having a long service life of a lamp and which is superior in its moldability, an electrode for the fluorescent discharge tube and the fluorescent tube provided with the electrode. SOLUTION: The electrode alloy for the fluorescent discharge tube is formed by Ni alloy, containing 1.0 to 3.0 mass% in total weight of one or two type(s) of elements selected from Nb or Ta, and the remainder substantially from Ni. The electrode for the fluorescent discharge tube 2 is provided with a tube part 3 with one end open and an end plate part 4, sealing the other end of the tube part 3. The end plate part 4 is formed thicker than the wall thickness of the tube part 3. A recessed part 6 for aligning a conductor for feeding power can be formed in a state concentric with he tube 3 in the end plate part 4. COPYRIGHT: (C)2004,JPO&NCIPI
