Summary:PROBLEM TO BE SOLVED: To obtain a low-temperature thermal storage medium which has a melting point near a specified temperature, is stable in the change in concentration, and utilizes the latent heat of fusion by blending an alkali metal succinate and water at a specified ratio. SOLUTION: An alkali metal succinate in an amount of 11-29 wt.% is blended with water in an amount of 89-71 wt.%. This heat storage material has a melting point near -5 deg.C. The alkali metal succinate used comprises a mono or di alkali metal succinate, wherein the alkali metal preferably comprises sodium or potassium. To be concrete, disodium succinate or monosodium succinate is preferably used. If necessary, a supercooling inhibitor may be blended. The supercooling inhibitor used preferably comprises silver iodide, potassium bromate or tripotassium phosphate. Thickening agent(s) comprising a waterinsoluble water-absorbent resin and/or a carboxymethylcellulose or the like may also be blended.
