PROBLEM TO BE SOLVED: To provide a heat storage material composition inhibiting supercooling with keeping sufficient latent heat of crystallization by containing a specific sugaralcohol such as erythritol and an amide compound of a long chain fatty acid. SOLUTION: The objective composition effectively utilizing erythritol, mannitol or galactitol as a high-temperature type heat storage material accelerating crystallization of the heat storage material without sacrificing latent heat of crystallization by containing at least one kind of sugaralcohol selected from erythritol, mannitol and galactitol and 0.01-30wt.%, preferably 0.3-15wt.%, more preferably 0.3-10wt.% of an amide compound of a 212C long chain fatty acid, preferably lauric acid amide, palmitic acid amide, stearic acid amide or behenic acid amide. |
