摘要： A spark plug includes a cylindrical metallic shell having a shoulder portion, and a tubular insulator having a stepped portion which rests on the shoulder portion within the metallic shell. The insulator has a rear half made of aluminum oxide and a front half made of aluminum nitride, the rear half having a protrusion, while the front half having a housing, and tightly joining the protrusion within the housing. An overlapping portion of the protrusion and the housing is at least partly located in a plane which is perpendicular to a longitudinal axis of the center electrode, the plane passing through the shoulder portion of the metallic shell.

摘要： In a sintered ceramic body used for an insulator of a spark plug, magnesium (Mg) is uniformly diffused into grains of a nitride-based ceramic body. An amount of the diffused magnesium (Mg) is within a range from 20 ppm to 100 ppm which is calculated by reducing the magnesium (Mg) to its oxidized component.
