PROBLEM TO BE SOLVED: To provide a high-precision temperature sensor capable of measuring a temperature in a corrosive fluid or corrosive atmosphere without being affected by the variation of ambient electric field. SOLUTION: The high-precision temperature sensor includes a temperature measurement element 100, a protective tube 12 made of metal protecting the temperature measurement element 100, a signal line 13 having one end connected to the temperature measurement element 100, a shield line 14 shielding the periphery of the signal line, and an exterior member 15 consisting of an insulating protective member covering the protective tube 12. The temperature sensor measures the temperature in the corrosive fluid or corrosive atmosphere without being affected by the variation of ambient electric field by means of the continuity between the shield line 14 and the protective tube 12.
