Summary:PROBLEM TO BE SOLVED: To obtain a cold storage material excellent in supercooling-preventing effect by including a sodium chloride aqueous solution and sodium carbonate. SOLUTION: This cold storage material contains (A) preferably 5-30 wt.% sodium chloride aqueous solution as a cold storage medium and (B) sodium carbonate (e.g. sodium carbonate octahydrate) as a supercooling-preventing agent, respectively. The component B is preferably contained in an amount of 1-20 pts.wt. based on 100 pts.wt. component A. The cold storage material preferably shows phase change phenomenon within the temperature range of -40 to -2 deg.C. Furthermore, the cold storage material is obtained by compounding, e.g. pure water or ion exchange water with sodium chloride at a prescribed amount to sufficiently mixing these components and then compounding the mixture with sodium carbonate in a prescribed amount to sufficiently mixing these components.
