PROBLEM TO BE SOLVED: To obtain a temperature measuring sensor which is excellent in voltage resistance property and thermal responsiveness and makes breaking of wires hardly occur. SOLUTION: A temperature measuring part 27 has a temperature measuring element for performing conversion into a measurement signal having a level in accordance with conductive heat, and a lead wire 29 for outputting the measurement signal. A cable 31 is connected to the lead wire 29 of the temperature measuring part 27 and outputs the measurement signal outside. A tube 37 made from synthetic resin into which the temperature measuring part 27 is inserted covers the sensor from the temperature measuring part 27 to an end of the cable 31. The outer covering 39 is made up of corrosion-resistant and heat-resistant synthetic resin and covers the whole of the synthetic resin tube 37 and the end of the cable 31 from the tip side opposite to the direction of leading out of the lead wire 29 in the temperature measuring part 27, and is adhered. The synthetic resin tube 37 is molded from thermoplastic heat-resistant synthetic resin or thermosetting heat-resistant synthetic resin having a melting temperature at least 1.2 times that of the outer covering 39 or higher.
