As a vacuum heat insulating panel, as disclosed in JP-A-58-50394 (a method for manufacturing a heat insulating plate), an air-permeable packaging bag is filled with powder, and the bag is covered with a surface material and a back material. A method of manufacturing a heat-insulating panel by putting it in a bag and sealing it in a vacuum state is disclosed.However, if the surface material and the back surface material of this outer bag are made of only plastic, gas invades from the surface of the outer bag. However, there is a problem that the degree of vacuum is deteriorated (the thermal conductivity is deteriorated), and if metal foils are laminated on the front surface material and the back surface material respectively to prevent the invasion of gas, the heat insulation panel has a peripheral edge portion. There is a problem in that it conducts thermally and the heat insulation performance deteriorates.

By sticking the metal foil composite plastic film on the outer surface or inner surface other than the adhesive part,
Alternatively, both the surface material and the back surface material do not include a metal foil and are formed by a metal deposition layer composite plastic film having a metal deposition layer on the inner surface, and the metal foil is formed on the outer surface or inner surface other than the heat-bonded portion of the surface material. Sealed by attaching a composite plastic film (when the metal foil composite plastic film is attached to the outer or inner surface of the surface material, there is a perforation within the range where the film of the surface material is attached) It is possible to obtain a vacuum insulation panel having very little thermal conduction in the peripheral portion of the bag.

This is probably because the continuous film was not formed.

A sealant layer 5 is laminated via an adhesive layer 4 on a surface layer 3 having a metal vapor deposition layer 2 formed on its inner surface. Here, the metal deposition layer 2 can be formed by depositing a metal such as aluminum on the surface layer 3 by a known method. The metal vapor deposition layer 2 preferably has a thickness of 300 to 1000A, particularly 500 to 800A. A film having heat resistance such as polyester, polyamide and polypropylene is used as the surface layer 3, and the thickness thereof can be usually 5 to 40 μm. The surface layer 3 may be a single layer or a composite layer of these plastic films. The sealant layer 5 is made of polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyacrylonitrile or the like and has a thickness of 15 to 3

を特徴とする真空断熱パネル。3. A vacuum heat insulation panel in which a heat insulating material is vacuum filled in a hermetically sealed bag formed by adhering four edges of a front surface material and four edges of a back material with a heat-bonding portion, and the back material is a metal foil composite plastic film. In addition to the above, the surface material is formed of a metal-deposited layer composite plastic film which does not include a metal foil and has a metal deposition layer on the inner surface, and the surface material is formed on the inner surface of the surface material other than the heat-bonded portion. And the surface material has perforations within the range to which the metal foil composite plastic film is attached.

ることを特徴とする真空断熱パネル。4. A vacuum heat insulation panel in which a heat insulation material is vacuum filled in a sealed bag formed by bonding four circumferences of a front surface material and four circumferences of a back surface material with heat-bonding portions, and both the front surface material and the back surface material are made of metal. Formed by a metal vapor deposition layer composite plastic film having no metal foil and having a metal vapor deposition layer on the inner surface, and sticking the metal foil composite plastic film on the inner surface other than the heat-bonded portion of the surface material, and the surface material. Has a perforation within a range where the metal foil composite plastic film is attached.
