<p><P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulating material having a high heat insulating effect by providing a reinforcing material to the force in a thickness direction in the vacuum heat insulating material divided into a plurality of sealed chambers. <P>SOLUTION: The constitution of the vacuum heat insulating material 1 has reinforcing skeleton members 6 of resin, metal, or the like disposed in a partial or an entire region of recessed clearance parts 5 formed of clearance parts between core material parts 3. There is a possibility of obtaining no sufficient heat insulating effect because the vacuum heat insulating material is weak to the force in the thickness direction and crushed when the force is applied thereto, but since the reinforcing skeleton members 6 of resin, metal, or the like are disposed at the partial or entire region of the recessed clearance parts 5 formed of the clearance parts between the core material parts 3, the force in the thickness direction is held by the reinforcing skeleton members 6 to prevent heat insulating from being not effected due to crushing. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
