摘要： [Objective] To provide a spark plug which is configured such that an insulation member, from which a center electrode projects, is pressed frontward and held in a metallic shell, and is fixed by means of crimping the rear end of the metallic shell, and which can prevent a drop in gas tightness between the metallic shell and the insulation member due to a difference in thermal expansion therebetween.[Means for Solution] In a spark plug in which a mating shaft portion (10) of an insulation member (1) is loose-fitted into a mating hole portion (30) of a metallic shell (21), a filler (41) for maintaining gas tightness is charged between the outer circumferential surface of the mating shaft portion (10) and the inner circumferential surface of the mating hole portion (30). Despite the thermal expansion difference, the gas tightness is maintained, because the filler (41) for maintaining gas tightness is charged between the inner and outer circumferential surfaces.

A ground electrode 30 includes a ground electrode base material 35 and a projecting shape section 36. The projecting shape section 36 is connected by resistance welding to an opposite surface 32 of the ground electrode 30 so as to be opposite and project towards the leading end of a center electrode 20. The ground electrode base material 35 and the projecting shape section 36 are formed from a material that is composed of the same metal (for example, nickel) as a main component and have a relation of formulas (1) and (2) described below. In formula (1), the specific resistance of the ground electrode base material 35 is R (μΩcm) and the specific resistance of the projecting shape section 36 is S (μΩcm). The specific resistance R>the specific resistance S . . . (formula 1), the specific resistance R− specific resistance S≧20 . . . (formula 2). Accordingly, fusion of the ground electrode base material 35 that has a larger volume than that of the projecting shape section 36 can be expedited and the welding strength can be enhanced.

摘要： A spark plug is provided capable of speedily burn off carbon adhered on an insulator. With this spark plug, in order to improve the temperature rise performance of a front end side of an insulator 10, an amount of protrusion H (mm) of the insulator 10, a front-end side volume Vi (mm3) of the insulator 10, and a front-end side volume Vc (mm3) of a center electrode 20 are respectively defined. In consequence, it is possible to improve the recovery property of carbon fouling while retaining the voltage resistance of the insulator 10 and the durability of the center electrode 20. In addition, since the recovery property of carbon fouling improves, it is possible to prevent the occurrence of side sparks generated from the center electrode 20 to a metal shell 50 along the insulator 10, thereby making it possible to stably ensure proper ignition of an air-fuel mixture.
