<p>PROBLEM TO BE SOLVED: To facilitate the handling of sealing part of a vacuum heat insulating material and to provide performance for maintaining of vacuum state for long period and reliable heat insulating effects. SOLUTION: In this heat insulating panel, a recessed part 520 to accept a sealing part 530 is provided on the side of a core material 51 of a vacuum heat insulating material 50. The sealing part 530 is constructed not to stick out of the vacuum material 50. For the construction of the heat insulating panel, it is planned to make the handling of the sealing part 530 easy, not to cause vacuum destruction by damage, to maintain the vacuum state of the vacuum heat insulating material 50 for long period, and to form a panel with reliable heat insulating effects.</p> |
