Therefore, an increase in gas intrusion into the interior can be reduced, deterioration of the heat insulating performance of the vacuum heat insulating material 4 can be suppressed, and further long-term use is possible. In addition, since the ultraviolet blocking agent 9 is only applied after the vacuum heat insulating material is manufactured, it is not necessary to prepare a vacuum heat insulating material dedicated to the shielding member, and the production cost is reduced.

  As the ultraviolet cut agent 9, since the metal powder has a low emissivity and has an excellent function in the ability to reflect infrared rays, the radiant heat transmitted to the surface of the heat insulating material is effectively suppressed, and the heat insulating performance is improved. In particular, silver, aluminum, etc. with low emissivity are effective.

  Since the inorganic powder has a function of reflecting infrared rays, the radiant heat transmitted to the surface of the heat insulating material is effectively suppressed, and the heat insulating performance is improved. There is also an advantage that the solid thermal conductivity is relatively lower than that of the metal powder. In particular, nitrides such as silicon nitride and boron nitride, and carbides such as silicon carbide and boron carbide are effective.

  Since the metal oxide has an action of scattering and reflecting infrared rays, the radiant heat transmitted to the surface of the heat insulating material is effectively suppressed, and the heat insulating performance is improved. There is also an advantage that the solid thermal conductivity is relatively lower than that of the metal powder. In particular, titanium oxide, tin oxide, antimony-doped tin oxide, tin-doped indium oxide, and the like are effective.

The incident infrared rays are incident on the bonded portion and the non-bonded portion of the adhesive, respectively. At this time, a part of the infrared ray incident on the bonded portion is absorbed by the infrared absorbing action of the adhesive and is conducted as heat to the infrared reflecting layer, but no infrared ray is absorbed because there is no adhesive in the non-bonded portion. Thus, by apply | coating an adhesive partially, the infrared absorption factor of a radiation heat conduction suppression film can be reduced, and heat conduction by radiation can be suppressed (Embodiment 5).
