どの製造コストが高くなるという問題がある。However, in the vacuum heat insulating panel, each plate member is generally formed as thin as possible for the purpose of reducing heat conduction as much as possible. Therefore, it is very difficult to position each plate member at a predetermined position with high accuracy because it easily bends in the state before joining. It should be noted that this problem becomes more prominent as the vacuum insulation panel to be formed becomes larger. Therefore, in order to form a large-sized vacuum heat insulation panel, a large jig is required to position the plate member with high accuracy, and there is a problem that manufacturing costs such as equipment costs increase.

どの製造コストが高くなることを防止できる。As is apparent from the above description, in the vacuum heat insulating panel of the present invention, the flat plate member and the side plate member, which are thin metal plates that easily bend, are joined together through the frame member. When positioning and welding each plate member, even if pressed against the frame member, the plate members are not bent. Therefore, it is possible to easily perform highly accurate positioning without using an expensive jig for highly accurate positioning. Therefore, it is possible to prevent the manufacturing cost such as equipment cost from increasing.
