PROBLEM TO BE SOLVED: To provide a hygrometer constituent member capable of preventing the corrosion of a heat transfer member and the falling of a temperature detection part in a measurement space, and accurately measuring temperature to be used for a humidity arithmetic operation.SOLUTION: A hygrometer constituent member includes: a heat pipe 11 having a first portion 11a disposed in a measurement space 101 and a second portion 11b disposed in an external space heat-insulated from the measurement space 101; a temperature sensor 12, mounted on the surface of the first portion 11a of the heat pipe 11, for detecting the temperature of the surface of the first portion 11a; a protection pipe 14 for covering the first portion 11a of the heat pipe 11 and the temperature sensor 12; and a heat radiation part 13, connected to the second portion 11b of the heat pipe 11, for receiving heat from the second portion 11b and radiating heat to the external space. The first portion 11a of the heat pipe 11 is thermally connected via a filler 15 to the protection pipe 14. |
