PROBLEM TO BE SOLVED: To attain greater improvement of response characteristics in a temperature sensor having a thermistor element held in a metal tube. SOLUTION: The temperature sensor 1 has a sheath member 8 connected to the thermistor element 2 and held inside the cylindrical metal tube 3 having blocked front end side. The metal tube 3 includes a small-diameter portion 33 located on the front end side and entirely having an inner diameter smaller than the outer diameter of the sheath member 8, and a large-diameter portion 36 located on the rear end side of the small-diameter portion 33 and having a diameter larger than the outer diameter of the small-diameter portion 33. While a thermistor sintered body 21 is held in the small-diameter portion 33, cement 10 is filled in between the front end of the thermistor sintered body 21 and the front end of the inner wall of the metal tube 3, on the front end side viewed from the rear end surface of the thermistor sintered body 21.
