Abstract
By using a core made of laminated sheets of inorganic fibers having a particular shape and composition as part of a vacuum heat insulator for a heat insulation box, a heat insulation box excellent in long-term heat insulating properties and productivity can be provided. The vacuum heat insulator can be shaped easily. Therefore, a vacuum heat insulator suitable for a required heat insulation portion can be produced easily and applied to a heat insulation box. This property can increase coverage of the vacuum heat insulator on the heat insulation box, thus improving heat insulating properties of the heat insulation box. This can improve heat insulating properties and productivity of a refrigerator, thermal storage box, cold storage box, or vending machine, and contribute to energy savings.
