摘要： In a spark plug having a precious metal tip joined to the front end portion of a ground electrode, the stable junction state of the precious metal tip is guaranteed for a long time. A precious metal tip 32 on the side of a ground electrode 27 is not directly joined to the front end portion of the ground electrode 27 but indirectly joined with a mounting part 51 interposed therebetween. The mounting part 51 includes a base part 53 which has a disc shape and is provided with a flange part 52 on its outer periphery and a protruding part 54 which protrudes from the base part 53 and has a columnar shape. First, in the state where the precious metal tip 32 is in contact with the protruding part 54 of the mounting part 51, laser welding or the like is performed thereon to form a fused part 42 and obtain a complex, and the base part 53 of the mounting part 51 is joined to a flat surface of the ground electrode 27 by resistance welding. The grain size of the grains of the mounting part 51 in the vicinity of the fused part 42 is smaller than the grain size of the grains thereof in the vicinity of the ground electrode 27, and the grain size of the grains of the flange part 52 of the mounting part 51 is smaller than the grain size of the grains of the protruding part 54.

摘要： A method of manufacturing a spark plug wherein a tip having a burr-free surface is more reliably welded to a ground electrode, to thereby realize an excellent joint strength. The spark plug includes a center electrode, a ground electrode, and a ground-electrode-side tip joined to the ground electrode through its joining surface. The method of manufacturing includes a tip forming step and a tip joining step of resistance-welding the ground-electrode-side tip to the ground electrode. A wire rod having a reference surface is formed, and the wire rod is cut by moving a cutting blade from one edge of the reference surface with respect to the width direction thereof toward the other edge of the reference surface with respect to the width direction, thereby obtaining the ground-electrode-side tip. At least a portion of the reference surface is joined to the ground electrode, whereby that portion becomes the joining surface.
