The purpose of the present invention is to provide a heat storage material having improved heat storage performance, the heat storage material being endowed with a preservative function. A heat storage material, characterized in having an inorganic salt aqueous solution, and a preservative that is endowed with a preservative function and that increases the phase transition time at the melting point of the inorganic salt aqueous solution, the preservative being dissolved in the inorganic salt aqueous solution. The preservative contains methylchloroisothiazolinone, methylisothiazolinone, and/or sodium chlorate. The concentration of the preservative is from 0.05 wt% to 0.1 wt%. The inorganic salt aqueous solution is a potassium chloride aqueous solution, a mixed aqueous solution of potassium chloride and potassium bicarbonate, or an ammonium chloride aqueous solution.read more
