    摘要: In a spark plug for an internal combustion engine oil is applied onto at least either the surface of an intermediate body portion (7) of an insulator (2) or the surface of an intermediate hole portion (10) of a metallic shell (8), thereby forming an oil film (11). Since the oil film has a dielectric constant falling between those of the insulator and an ambient air layer, a great change in dielectric constant between the insulator and the ambient air layer is eased. Also, since the oil film is of liquid, the oil film smooths a dent or protrusion or a fine defect such as crack present on the surface of the intermediate body portion of the insulator. Thus, electric field concentration is suppressed, thereby preventing dielectric breakdown caused by such a dent, protrusion or fine defect.

    摘要: In a spark plug which has a center electrode disposed in a metallic shell through an insulator so that a front end of the center electrode forms a spark gap with an outer electrode extended from the metallic shell, the outer electrode has a heat-conductive core metal cladded by a matrix metal which is made from nickel-based alloy containing 10 ∼ 20 wt% chronium. A platinum tip is welded to the outer electrode so that a spaced distance between a circumferential edge of the welded portion and a front end of the core metal falls within a range from 0.0 mm to 2.0 mm.
