摘要： PROBLEM TO BE SOLVED: To secure both thermal shock resistance property and voltage- withstanding property of a spark plug for an internal combustion engine.
SOLUTION: With the spark plug using a high-pressure-molded insulator 20, surface roughness of the insulator 20 at a part contacting with a packing 60 is made 10 μm or less in ten-point average, so that a contact area with the packing 60 is increased and heat transmitted from combustion gas to the insulator can be more easily released to a housing 10 through the packing 60. In other words, an excellent heat dissipation is realized. On this account, temperature rise of the insulator 20 at the part contacting the packing 60 is made small to improve the thermal shock resistance property of the insulator 20.

摘要： PROBLEM TO BE SOLVED: To restrain separation between a heating element and a lead wire and improve reliability in a ceramic glow plug in which the length L1 in the axial direction from one end of a case in a ceramic substrate to the end of the lead wire at the contacting side between the heating element and the lead wire, is not less than 7 mm. SOLUTION: The bar-like insulating ceramic substrate 6 is held in a cylindrical pipe 5 which is held by a housing 2. A U-shaped ceramic heating element 7 which can be charged with electricity and exothermic is embedded inside the portion of the substrate 6 protruded from the pipe 5. Two lead wires 8a, 8b made of tungsten or the like are connected to the heating element 7 so that they can conduct current. The region where the maximum temperature portion of the heating element 7 exists when heat is generated, is rendered to account for not more than 31% of a length L2, in the axial direction of the substrate 6, from a point 7a of the heating element 7 to the end of the lead wires.
