PROBLEM TO BE SOLVED: To perform objective evaluation by surely detecting even a mixed odor which is hardly detected by a conventional measuring device using an odor sensor. SOLUTION: A sample gas as a measured object is introduced to a column 10 of a GC part 1 to separate odor components in terms of time, and then introduced to a MS part 2 and an odor discrimination part 3 using the odor sensor 32 in parallel. A data processing part 51 creates a chromatogram and mass spectral on the basis of a detection signal obtained by a detector 24 of the MS part 2, and calculates the similarity of each odor component and the contribution of odor index to standard odor on the basis of a detection signal obtained by a detecting circuit 33 of the discrimination part 3. Then a similarity radar chart of the component associated with a peak represented by the chromatogram is displayed on a screen of a display part 53. As the components are separated in terms of time at the GC part 1 even in a case of the mixed odor including a large amount of component and a very small amount of component, the odor component can be surely objectively detected by the odor discrimination part 3.
