We report the preservation of CO_2 clathrate hydrate in the samples coexisting with trehalose. The samples having 1.0 mm and 5.6-8.0 mm diameter were prepared from trehalose aqueous solution of 0.05 or 0.10 mass fractions and stored at 243.2 K and 253.2 K for three weeks. The preservation for 5.6-8.0 mm diameter samples was better than that for 1.0 mm diameter samples. The preservation with trehalose was superior to that with sucrose and comparable to that without sugars. It is inferred that existence of aqueous solution in the samples is a significant factor of the preservation in the presence of sugar.
