Abstract: A protruding length L1 that is a distance between an inner circumference of a flow path through which fluid flows on an axis of a temperature sensor disposed in the flow path and the center of said temperature sensitive device is 50 mm or more. A protruding location that is a distance between an inner circumferential surface of the flow path and the center of said temperature sensitive device on a cross section extending perpendicular to the axis of said flow path through the center of said temperature sensitive device is defined as L1?. A flow path width that is a distance between intersections of the axis of the temperature sensor with the inner circumferential surface of said flow path when the temperature sensor is projected onto said cross section is defined as D1. A relation of L1?/D1 is specified as a function of the value of D1, thereby reducing heat transfer in an exhaust temperature sensor and enabling the temperature to be measured accurately.
