<p><P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulating material that prevents degradation of heat insulation performance, retains the shape, and is easy to handle. <P>SOLUTION: The vacuum heat insulating material 10 is a substantially rectangular flat plate. The vacuum heat insulating material 10 includes: frame members 13 arranged along the four sides of the vacuum heat insulator; a core member 12 disposed within a space defined by the frame members, and forming vacuum heat insulating parts 11; and a thermally deposited layer of a synthetic resin-based material provided on the side of the core member and the frame member. The vacuum heat insulating material 10 is also provided with gas barrier packaging material 14, 15 for covering the front and back sides and the outer peripheral side of the core member, and having sealing parts 16 for encasing the frame members at the four sides of the vacuum heat insulator. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
