The best mode aims to provide a thermal storage medium that improves the efficiency of heat exchange between the thermal storage medium and the cooling medium liquid in the cooling medium body, and that prevents supercool of the aqueous solution which produces hydrate. A large thermal storage capacity is attained using the latent heat of hydrate in the cooling medium body. By forming slurry of hydrate, the fluidability of the hydrate increases the efficiency of the heat exchange with cooling medium liquid. By sealing fine particles in the cooling medium body, the super-cool of aqueous solution is prevented. By changing position of the cooling medium body or by other means, the aqueous solution is agitated to keep the fine particles disperse and float in the aqueous solution, thus preventing the degradation of effect to prevent supercooling. Furthermore, a method for producing hydrate cooling medium body that can be generated at higher temperatures than the temperature of ice without using a thermal storage medium is suitably used in thermal storage system such as air-conditioners without using a special coolant.
