摘要： The object of the invention is to provide a spark plug including a central electrode and/or a ground electrode, which can suppress generation of corrosion-like generated foreign substances while maintaining high thermal conductivity and high strength.The spark plug according to the invention is a spark plug including a central electrode and a ground electrode provided to have a gap between the central electrode and the ground electrode with at least one of the central electrode and the ground electrode formed from an electrode material including 96% by mass or more of Ni, in which the electrode material includes a total content of from 0.05% by mass to 0.45% by mass of at least one selected from a group consisting of Y and rare earth elements, 0.05% by mass or more of Mn, and a total content of 0.01% by mass or more of at least one selected from a group consisting of Ti, V, and Nb, and the ratio (a/b) of the total content (a) of Ti, V, and Nb to the content (b) of Mn is from 0.02 to 0.40.
