PROBLEM TO BE SOLVED: To propose an ignitor conduit easy to manufacture while ensuring a gas passage by forming an insulated conductor inserted into the ignitor conduit to have a polygonal sectional shape. SOLUTION: A coated conductor 3 including an insulator 5 for covering a conductor 4 molded in a substantially square shape is inserted into a circular sectional gas tube 2. According to this, even if the gas tube 2 is deformed at the time of fixing the conduit 1 by a pressing part, the gas passage can be ensured by the square insulator to stabilize ignition, and a base can be simplified. Therefore, a reduction in manufacturing cost and an improvement in strength of coating can be attained. COPYRIGHT: (C)2006,JPO&NCIPI
