PROBLEM TO BE SOLVED: To provide a humidity detector capable of suppressing deterioration in detection accuracy of a glass temperature when time has elapsed after manufacturing.SOLUTION: In a humidity detector 10, a circuit board 11 is supported by a heat conduction member 30. An elastic member 40 comes into contact with a case 12 and the circuit board 11 to depress the circuit board 11 to a window glass 50 side by an elastic force on a regular basis. The elastic member 40 is a plate spring. The outer periphery of the circuit board 11 is supported by a base 15. Heat conduction on a contact surface can be maintained because the circuit board is depressed to the window glass 50 side by the elastic member 40 even when the heat conduction member 30 is worn out and stress becomes small through time degradation.SELECTED DRAWING: Figure 1 |
