Abstract
Provided is a heat storage material composition comprising at least one sugar alcohol selected from erythritol, mannitol and galactitol, and a salt which is sparingly soluble in the sugar alcohol. The heat storage material composition of the present invention can stably be used for a long period of time since the crystallization temperature is not decreased even if heat absorption and heat radiation are repeated.
