The Rare Sugars exist naturally and have many kinds (more than 50). They have good effect for health such as prevention of increasing a blood-sugar level after eating, suppression of fat accumulation, suppression of increasing the blood pressure, and antioxidative effect etc. It is in the spotlight for many people especially for those who are in the metabolic syndrome. There are few related papers concerning the marketing research and its utilization of this matter. In this paper, a questionnaire investigation is executed in order to clarify consumers' current condition and their consciousness, and to seek the possibility of utilizing the rare sugars. Correspondence Analysis was executed based on that. 5 clusters could be confirmed in the "Common part + Positive part" analysis. We could also confirm 3 clusters in the "Common part + Negative part" analysis. We could grasp the relation among questions group on the whole. Mathematics Subject Classification: 62H15
