In this study, intermittent aroma stimulus while working has been proposed to improve their intellectual concentration and work efficiency and an evaluation experiment was conducted where concentration index was measured under aroma stimulus condition and no aroma condition. As the result, it was found that the intellectual concentration under the aroma stimulus condition was significantly higher than that under no aroma condition.
