<p><P>PROBLEM TO BE SOLVED: To provide a heat insulating material excellent in handleability and heat insulating performance, and to provide an insulated box using the same. <P>SOLUTION: This heat insulating material is formed by sealing a core material 3, which is structured by laminating several sheets of fiber aggregates 3a, in a gas barrier container, and making the inside vacuum. The fiber aggregate 3a is composed of an embossed unwoven fabric. Since the core material 3 is formed into a layered structure of the embossed unwoven fabrics, the core material 3 is easy to be handled, and heat insulating performance is improved. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
