Abstract
A spark plug (100) having a ground electrode (30), a noble metal tip (31) having a front end (37) that projects forward of a front end portion (33) of the ground electrode (30), and a center electrode (20). When S1 represents an area of an overlap region in which a region onto which the center electrode (20) is projected overlaps a region onto which the noble metal tip (31) is projected when the center electrode (20) and the noble metal tip (31) are projected onto an imaginary plane (VP) perpendicular to a center line (CL1) of the center electrode (20), and S2 represents an area of an overlap region in which a region onto which the noble metal tip (31) is projected overlaps a region onto which the ground electrode (30) is projected when the noble metal tip (31) and the ground electrode (30) are projected onto the imaginary plane (VP), 0.22¤S1/S2¤0.68 is satisfied.
