In a temperature sensor (1), a pair of electrode wires (25) of a thermistor element (21) are formed of a material prepared by adding strontium to platinum or a platinum alloy and without addition of zirconia or a like oxide. Rear end portions of the electrode wires (25) formed of the above-mentioned material and front end portions of sheath core wires (3) are laser-welded to one another in an overlapping condition. |
