Abstract
Provided is a fluorescent lamp electrode, having excellent sputtering resistance and able to retain excellent dark-start characteristics over a long period of time when used as an electrode in a cold cathode fluorescent lamp, and which can be produced inexpensively. A fluorescent lamp of this invention has a prolonged life resulting from the use of said electrode. Said electrode is made by dispersing in a nickel or nickel alloy base one or more rare earth metals selected from among lanthanum, cerium, yttrium, samarium, praseodymium, niobium, europium and gadolinium in the form of a precipitated boride phase.
