The present invention, in an embodiment thereof, provides a latent heat storage material containing a supercooling inhibitor that, if added to an aqueous solution of an inorganic salt including sodium chloride, restrains supercooling by unfailingly precipitating as crystals upon cooling and therefore only marginally lowers the melting point and reduces latent heat. The latent heat storage material contains: an aqueous solution of sodium chloride; and a eutectic aqueous solution of sodium chloride and disodium hydrogen phosphate in an amount that, in comparison with the eutectic aqueous solution of sodium chloride, is greater than or equal to an amount that gives a saturation concentration at 0 C. This arrangement makes a sufficient amount of latent heat available for cooling white restraining supercooling, by using a latent heat storage material containing a supercooling inhibitor that restrains supercooling by unfailingly precipitating as crystals upon cooling and that therefore only marginally lowers the melting point and reduces latent heat.
