<p>PURPOSE:To provide the vacuum heating insulating material displaying excellent heat insulating performance and assembled smoothly. CONSTITUTION:After accommodating a heat insulating plate in a flexible container with gas barrier performance, the container is evacuated. The container thereby adheres closely to the heat insulating plate to seal, thus forming vacuum heat insulating material 1. In this vacuum heat insulating material 1, at least one of parallel end faces along the thickness direction of the heat insulating plate is provided with such shape as to cross an imaginary straight line in the thickness direction of the heat insulating plate.</p> |
