Abstract
A vacuum insulation material includes a pair of gas barrier exterior materials, a core material including a cellulose structure having porosity of greater than or equal to about 80% under reduced pressure of about 1 Pa, where the cellulose structure has a unit length of greater than or equal to about 1 μm and less than or equal to about 5 mm in the heat-insulation direction, and the method of manufacturing the same, and a gas adsorption agent, where the core material and the gas adsorption agent are interposed between the pair of gas barrier exterior materials and sealed inside of the pair of gas barrier exterior materials under reduced pressure.
