An odor-sensor-data correcting device 1 for suppressing a measurement error due to the individual difference among odor sensors includes: a calculation unit 2 that calculates a correction coefficient on the basis of first odor data indicating a first odor and second odor data obtained as a result of an odor sensor measuring the first odor; and a correcting unit 3 that corrects, on the basis of the correction coefficient, third odor data obtained as a result of the odor sensor measuring a target odor.
