PROBLEM TO BE SOLVED: To provide a temperature sensor for preventing lead wires of a sensor element from becoming thin and stably maintaining the accuracy of detected temperatures. SOLUTION: The temperature sensor includes a sensor element unit 10 having a temperature sensing body 2 whose electric resistance varies with the temperature, a pair of lead wires 4 electrically connected to the temperature sensing body 2, and a covering material 5 sealing the temperature sensing body 2 and a predetermined area of the lead wires 4, the lead wires 4 extracted from a sealing end 6 of the covering material 5; a metal protective tube 20 housing the sensor element unit 10 except a part of the lead wires 4; and a ceramic shielding body 7 located between the sensor element unit 10 and the metal protective tube 20 and surrounding the sealing end 6.
