PURPOSE:To prevent a heat accumulating material from leaking outside the titled heat accumulating body by a method wherein a vessel containing the heat accumulating material therein is covered or bonded with a porous substance such as a foaming material. CONSTITUTION:Microcrystalline wax consisting of the foaming material 1 such as foaming polyurethane impregnated with the heat accumulating material 2 is filled into the vessel 3 and the vessel 3 is covered with the porous substance 4. As a consequence, even when the vessel 3 is broken, an effluence of the heat accumulating material 2 from the vessel 3 is adsorbed by the porous substance 4 so that the safety and the availability of the heat accumulating body can be improved. |
