Abstract:
A spark plug includes a tubular metal shell that includes a metal-shell step portion extending in an inner circumferential direction, an insulator that is inserted in the metal shell, that includes a facing portion that faces the metal-shell step portion with an annular packing interposed therebetween, a center electrode that extends in the axial direction, that has a flange portion extending in an outer circumferential direction, and a seal body seals the insulator and the center electrode. In a section that contains the axial line and that is along the axial line, a distance L along the axial line from a rear end of the facing portion of the insulator to a rear end of a portion at which the flange portion is in contact with the insulator satisfies L≤1.1 (mm).

Claim (Index 2):
The spark plug according to  claim 1 ,\n \u03b8A+\u03b8B\u226590\u00b0 and L\u22650.5 (mm) hold, where \u03b8A represents an acute angle formed between a reference line perpendicular to the axial line and the portion at which the flange portion is in contact with the insulator in the section, and \u03b8B represents an acute angle formed between the reference line and a straight line connecting a front end of the facing portion and the rear end of the portion at which the flange portion is in contact with the insulator.
