    摘要： A spark plug includes a ceramic insulator, a center electrode, a metallic shell, and a ground electrode. The center electrode has a shoulder portion at a forward end portion, which tapers forward with respect to the axial direction. A noble metal tip is joined to the forward end portion of the center electrode through a fusion zone. A spark discharge gap is formed between the noble metal tip and the ground electrode. The shortest distance between the fusion zone and a forward end surface of the noble metal tip is 0.8-1.2 mm. The outside diameter of the fusion zone as measured at a forward end of the fusion zone is smaller than that as measured at a rear end of the fusion zone. An acute angle θ1 formed by a straight line L1 and a straight line L2 satisfies the relational expression θ1≦72°.

    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.
