Abstract:
A spark plug including a center electrode with a tip welded to a front end portion with a fused portion therebetween. The front end portion contains Ni, Cr, and at least one element selected from a group B consisting of Mn, Si, Al, Ti, rare earth elements, Hf, and Zr. Ni is present in the largest proportion, and Cr is present in the second largest proportion and in an amount of 12% by mass or more. The at least one element selected from the group B is present in a total amount of 0.1% by mass or more. The front end portion satisfies f/e≤0.15 and m/e≤0.015, where f is the Fe content, e is the sum of the Cr, Si, and Al contents, and m is the Mo content.

Claim (Index 3):
The spark plug according to  claim 1 , wherein\n the front end portion has a region where a plurality of crystal grains appear in a cross-section containing the axial line, a length of the crystal grains in the region in the direction along the axial line is longer than a length of the crystal grains in the region in a direction perpendicular to the axial line, and the front end portion satisfies Ha/Hb\u22650.36, where Ha is a Vickers hardness of the region in the cross-section after heat treatment at 900\u00b0 C. in an Ar atmosphere for 50 hours, and Hb is a Vickers hardness of the region in the cross-section before the heat treatment.
