Abstract
The present invention provides a vacuum heat-insulating block including a honeycomb core, wherein the block structure prevents the honeycomb core having a low bulk specific gravity from collapsing by atmospheric pressure, the block attaining flexibility and sound absorption property. The vacuum heat-insulating block 100 according to the present invention is basically composed of a core utilizing a plurality of layered honeycomb members 50 (formed by bonding a honeycomb core member 51 to a support plate 55) and covering the core with a cover member 70. Moreover, a woven or non-woven fabric 60 having air permeability is disposed between the layers of honeycomb core members 51.
