The present invention provides a thermistor-type temperature sensor equipped with a thermistor element having a thermistor section and electrode wires for acquiring thermistor signals that prevent breakage of electrode wires caused by high-frequency vibrations.;Thermistor element (10) is equipped with thermistor section (11) and electrode wires (12) and (13) made of a dispersion-strengthened material having for its main component platinum or platinum alloy, and is insulated and held in cylindrical metal case (40) having opening (42) on one end by means of insulating powder (50). A bottomed, cylindrical metal protective tube (60) houses metal case (40) so that its bottom (61) covers opening (42). Heat-resistant adhesive (70) is juxtaposed in a gap between metal case (40) and protective tube (60) so as to seal opening (42) to-prevent insulting powder (50) from spilling into this gap from opening (42).
