<p>PURPOSE: A getter material containing a gas absorbent wrapped by a moisture absorbent and a manufacturing method thereof are provided to prevent the surface of a gas absorbent from changing into a deactivation in a manufacturing process while removing moisture and gas existing inside of a vacuum heat insulating material. CONSTITUTION: A getter material containing a gas absorbent wrapped by a moisture absorbent includes a gas absorbent(131), a moisture absorbent(133), and a packing material. A moisture absorbent wraps the surface of the gas absorbent. A getter(130) prevents the deterioration of the gas absorbent during a manufacturing process. The gas absorbent includes a fine pore material. The gas absorbent includes more metal or metal oxide. The moisture absorbent includes one or more of CaO, CaCl_2, MgO, and silica gel. A packing material wraps the gas absorbent and the moisture absorbent.</p> |
