The purpose of this research is to investigate the diffusion state of odor of aromatic and to clarify the influence on the odor component and quality due to the difference in use period. We evaluated the odor by the olfactory measurement method, the sniffing GCMS and gas sensors. Gas sensors were used to clarify the indoor diffusion behavior of the odor. As results of the odor intensity and odor concentration, the value of the aromatic used for 4 weeks was lower than the new one. In the description of the impression of odor, as time passed, it became an abstract expression such as “oil-like” from concrete expression such as “lemon” “tree”. The odor component analysis using odor sniffing GCMS revealed that the area value of many chemical substances decreased for 4 weeks of use rather than new products, but the area values of hexanal and benzyl alcohol increased.
