PURPOSE: A high temperature sensor for exhaust gas is provided to rapidly detect a change of temperature because a compression plate portion absorbs more heat while sensing a temperature through enlarging a heating surface area. CONSTITUTION: A high temperature sensor for exhaust gas comprises a thermistor(30), wires(21,31) and a protective tube(10). The thermistor is a temperature measurement resistant of a sheath line(20). The wires connect the thermistor and sheath line. The wires are composed of two wires of an endmost portion of the sheath line and two wires of an endmost portion of the thermistor. The protective tube protects the sheath line and thermistor from outside. A leading end of the protective tube is compressed as the heating surface are widen so that a junction unit(11) is formed. A joint(12) of the upper and lower sides of the junction unit is sealed by welding.
