Abstract: An odor detection apparatus 100 includes a first odor sensor 10 provided with a sensitive membrane, a second odor sensor 20 provided with an identical sensitive membrane, and a control device 30. The control device 30 includes a sensor data acquisition unit 31 that acquires first sensor data output by the first odor sensor 10 and second sensor data output by the second odor sensor, a calculation processing unit 32 that calculates a difference between the first sensor data and the second sensor data, and a determination unit 33 that determines, when the sensitive membrane of one of the odor sensors is in a steady state, whether the sensitive membrane of the other odor sensor is in a steady state, based on the difference.
