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. 【課題】測定空間内部における伝熱部材の腐食および温度検出部の脱落を防止することができ、しかも、湿度演算に用いる温度を正確に測定することが可能な湿度計構成部材を提供する。【解決手段】湿度計構成部材は、測定空間１０１に配置される第１部分１１ａと、測定空間１０１から断熱された外部空間に配置される第２部分１１ｂとを有するヒートパイプ１１と、ヒートパイプ１１の第１部分１１ａの表面に取り付けられ、当該第１部分１１ａの表面の温度を検出する温度センサ１２と、ヒートパイプ１１の第１部分１１ａおよび温度センサ１２を覆う保護管１４と、ヒートパイプ１１の第２部分１１ｂに接続され、当該第２部分１１ｂから熱を受けて外部空間に放熱する放熱部１３とを備えている。ヒートパイプ１１の第１部分１１ａは、充填材１５を介して保護管１４に熱的に接続されている。【選択図】図２
