    • PROBLEM TO BE SOLVED: To suppress the leakage of exhaust gas from a component insertion hole of a housing.SOLUTION: In a projecting portion 103b of a retaining portion 103, a collar portion 33b of an insulation body 33 in which an ignition heater 32 is inserted is positioned. The retaining portion 103 is screwed on an upper flange portion 122 of an attaching base portion 102, and presses the collar portion 33b of the insulation body 33 downward. Between a lower surface of the collar portion 33b of the insulation body 33 and an upper surface of a second bulging portion 133 of a lower flange portion 123 of the attaching base portion 102, a collar portion sealing material 105 is interposed. A sealing property between a lower surface of a first bulging portion 131 of the lower flange portion 123 of the attaching base portion 102 and an upper surface of a housing 2 is ensured by welding. Even if exhaust gas in the housing 2 passes through a clearance between the housing 2 and the insulation body 33 and reaches the inside of a second space 107b, the leakage of the exhaust gas from the inside of the second space 107b is suppressed by welding and fixing between the lower flange portion 123 and the housing 2, and the collar portion sealing material 105.
