Title: LEAD WIRE
Abstract:
Disclosed is a lead wire for supplying electric power to an electrode part of a cold cathode fluorescent lamp, which is configured from a nickel alloy that contains not less than 0.0001% by mass but not more than 0.03% by mass of C, and not less than 1.0% by mass but not more than 9.0% by mass in total of one or more elements selected from among Mn, Si and Cr, with the balance made up of Ni and unavoidable impurities. By controlling the C content and containing the specific elements in the specific amounts, the strength of the wire itself, the strength of a welded portion and the solder wettability can be improved, while having excellent electrical conductivity and thermal conductivity. Also disclosed are a lead wire member comprising the lead wire, an electrode member, a cold cathode fluorescent lamp, and a wire suitable for the lead wire.
