1. An odor detection device, comprising:
an odor sensor to detect information on an odor emitted from a source;
environmental information measurement means for measuring information on an environment, correlated with an amount of water vapor contained in surrounding gas;
odor information collection means for collecting the information on the odor, detected by the odor sensor;
difference information acquisition means for acquiring difference information indicating a difference between the information on the environment surrounding the odor sensor measured in a state in which the information on the odor has not been detected by the odor sensor, the information on the environment surrounding the odor sensor measured in a state in which the information on the odor has been detected by the odor sensor, and the information on the environment surrounding the source; and
correction means for correcting the information on the odor, collected by the odor information collection means, based on the difference information acquired by the difference information acquisition means.
