Abstract:
An electrode of the spark plug includes a first melt portion formed between a body portion of an intermediate member and a noble metal tip; and a second melt portion that is formed, between a flange portion of the intermediate member and an electrode base material, at least at a position of intersection with an axial line of the noble metal tip. In a cross section including the axial line of the noble metal tip, when: a diameter of the noble metal tip is denoted by Tw; the shortest distance between the second melt portion and a boundary between the first melt portion and the intermediate member is denoted by S 1 ; and the longest distance between the second melt portion and the boundary between the first melt portion and the intermediate member is denoted by S 2 , 1.0 mm≤Tw≤1.2 mm and (S 2 −S 1 )≤0.3 mm are met.

Claim (Index 4):
A spark plug according to  claim 1 , wherein the electrode base material and the noble metal tip are a base material and a tip of the ground electrode.
