To prevent the separation of the tip (left out), and variations effectively. In at least one of the spark plug 1 includes a center electrode 5 and, further comprising a ground electrode (27) to form a spark discharge gap 33 is formed between the center electrode 5, the two electrodes (5, 27) the tip (31, 32) are welded. Tips 31 and 32 is the noble metal component of the content (A,% by weight) and the electrode (27, 5) of the noble metal component of a smaller thermal expansion coefficient than the electrode (27, 5) to which it is welded, the tip (31, 32) the difference (AB) of the content (B,% by weight) is not less than 50% by weight. Tips 31 and 32 and bounds the length of the electrode (27, 5) the intermediate layer (34, 35) perforated (38, 39) is present, the tip (31, 32) and the intermediate layer (34, 35) in between If the length L (㎜), the tip (31, 32) and the intermediate layer (34, 35) perforated (38, 39) in the direction along the boundary of a N (㎜), as 0.1≤N / L≤0.4 do.
