要約
(EN)
Disclosed is a spark plug which comprises a center electrode and/or a ground electrode that is capable of suppressing generation of an emergent corrosive material, while maintaining high thermal conductivity and high strength. Specifically disclosed is a spark plug, which comprises a center electrode and a ground electrode that is arranged at a distance from the center electrode, and wherein the center electrode and/or the ground electrode is formed from an electrode material that contains not less than 96% by mass of Ni. The spark plug is characterized in that the electrode material contains at least one element selected from the group consisting of Y and rare earth elements in an amount of 0.05-0.45% by mass (inclusive) in total, Mn in an amount of 0.05% by mass or more, and at least one element selected from the group consisting of Ti, V and Nb in an amount of 0.01% by mass or more, while having a ratio of the total content (a) of Ti, V and Nb to the Mn content (b), namely a/b of 0.02-0.40 (inclusive).
