PROBLEM TO BE SOLVED: To provide a chemical heat storage material excellent in durability and capable of exercising fully the ability thereof as a chemical heat storage system; and a production method thereof. SOLUTION: This chemical heat storage material has: a basket-shaped structure 5 having a large number of pores which is obtained by calcining a mixture of a clay mineral 2 and a combustible granular substance 3; and a chemical heat storage material 6 supported on the outer surface and in the inside of pores of the basket-shaped structure 5. The combustible granular substance 3 is preferably one type or two or more types of a coconut, a chip, a carbon black and a ketjen black. The clay mineral 2 is preferably sepiolite and/or palygorskite. The chemical heat storage material 6 is preferably a hydration reaction-type chemical heat storage material converted into an oxide according to a dehydration reaction and converted into a hydroxide according to a hydration reaction. The chemical heat storage material is preferably produced by further incorporating a thermal conductivity-enhancing material. The thermal conductivity-enhancing material is preferably a carbon nanotube. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a manufacturing method for a thermal storage material structure capable of preparing a thermal storage material structure having a small carbon content and being excellent in thermal storage/heat release property of the chemical thermal storage material.SOLUTION: In the manufacturing method for the thermal storage material structure, the thermal storage material structure is prepared using the chemical thermal storage material and an organic binder. The manufacturing method includes a dehydration step for dehydrating a part of the chemical thermal storage material by a dehydration reaction, a salt production step for producing a carbon dioxide gas by heating/decomposing the organic binder under an atmosphere in which a moisture content is fed by dehydration and producing a carbonate by reacting the produced carbon dioxide gas with at least a remained part of the chemical thermal storage material, and a removal step for being subjected to thermal decomposition of the produced carbonate to remove it.
