PROBLEM TO BE SOLVED: To provide an electrode for a cold-cathode discharge tube and an electrode assembly for a cold-cathode discharge tube each having high resistance to sputtering, capable of extending the electrode service life, using an inexpensive material and is thereby capable of reducing the electrode cost, and having proper workability. SOLUTION: This electrode for a cold-cathode discharge tube is formed of a Ni-Nb alloy, containing 6-32 wt.% of Nb and having a composition of unavoidable impurities and Ni in the remaining part. This electrode assembly 14 for a cold-cathode discharge tube is composed of a cup-shaped electrode 10, formed of a Ni-Nb alloy containing 6-32 wt.% of Nb and having a composition of unavoidable impurities and Ni in the remaining part, and a lead 12 fixed to the bottom surface of the electrode 10.
