PROBLEM TO BE SOLVED: To provide an electrode material for a spark plug with reduced consumption of the electrode and excellent durability. SOLUTION: The electrode material for a spark plug contains 0.5 to 1.5% of Si, 0.5 to 1.5% of Al, 0.05 to 0.5% of one or two components selected from the group consisting of Y, Nd and Sm, 0.8% or less of the total amount of Cr and Mn, and the rest consisting of Ni or inevitable impurities. The specific resistance of the material at normal temperatures is adjusted to 25μΩcm or less. COPYRIGHT: (C)2004,JPO&NCIPI
