A temperature sensor element in a temperature-measuring device using a thermocouple having excellent insulation property and having a simple assembly procedure is provided. The temperature sensor element comprises a temperature-measuring means consisting of a heat-resistant protective tube having a thermocouple inserted therethrough, compensating conduction means having connecting sections which connect a pair of extension sections of a thermocouple element extending from the protective tube respectively, and support means to join and hold mutually the temperature-measuring means and the compensating conduction means. The end of the protective tube and the compensating conduction means are held under the condition that they face the support means and that the extension sections of the thermocouple element and the connecting sections of the compensating conduction means are inserted into holding chamber means provided in the support means. Then the holding chamber means is filled with a filler which is hardened to bury and fix the end of the protective tube, the extension sections of the thermocouple, and the connecting sections of the compensating conduction means in the filler.
