This humidity detecting device is provided with a sensor case (82) disposed in a vehicle interior and a humidity sensor (86) detecting the relative humidity of air in the sensor case. Air in the vehicle interior flows around the humidity sensor in the sensor case through an air intake part from the outside of the sensor case. The humidity detecting device acquires airflow amount information correlated with the amount of air flowing around the humidity sensor (S40). The humidity detecting device acquires airflow direction information correlated with the direction of air flowing around the humidity sensor (S50). The humidity detecting device sets a correction coefficient configuring a dynamic compensator, which compensates for a response delay of the humidity sensor, on the basis of the airflow amount information and the airflow direction information, the response delay being caused by the sensor case and changed due to the amount and direction of air flowing around the humidity sensor (S60, S60B). The humidity detecting device corrects the detected value of the humidity sensor by means of the dynamic compensator set by a setting part in order to acquire the relative humidity of air which is in the vehicle interior and outside the sensor case (S90). |
