(57) Abstract: Provided is a heat storage material used around a body having excellent heat storage properties. SOLUTION: Melting point is -10 to 80 ° C, latent heat is 30 J /. A heat storage material used around the body having a solution viscosity of not less than 100 g / s and not less than 100 mm 2 / s at 50 ° C. This heat storage material When the outside air temperature rises, it absorbs heat and melts, and when the outside air temperature falls, it releases heat and solidifies. Therefore, the fluctuation of the outside air temperature is eased, a constant temperature is easily maintained, and the function as a heat storage material is exhibited. Further, since the material has a high viscosity, it is difficult for the material to flow out even when the material is melted. |
