HEAT INSULATING SHEET, HEAT INSULATING MATERIAL, METHOD OF MANUFACTURING HEAT INSULATING SHEET, AND METHOD OF MANUFACTURING HEAT INSULATING MATERIAL

摘要

It has been difficult to achieve weight reduction while satisfying a required insulation property in a heat insulating material configured by alternately stacking a metal vapor-deposited sheet and a net. A heat insulating sheet comprises: a first thermal conduction suppressing layer that suppresses thermal conduction; a first radiant heat reflecting layer that is placed on one surface side of the first thermal conduction suppressing layer and reflects radiant heat; and a protruding portion protruding from a surface of the first radiant heat reflecting layer on an opposite side of a surface on which the first thermal conduction suppressing layer is stacked, the protruding portion containing a resin at least on its surface.

1. A heat insulating sheet comprising:
a first thermal conduction suppressing layer that suppresses thermal conduction; a first radiant heat reflecting layer that is placed on one surface side of the first thermal conduction suppressing layer and reflects radiant heat; and a protruding portion protruding from a surface of the first radiant heat reflecting layer on an opposite side of a surface on which the first thermal conduction suppressing layer is stacked, the protruding portion containing a resin at least on its surface, wherein the first radiant heat reflecting layer has an opening on the surface on the opposite side of the surface on which the first thermal conduction suppressing layer is stacked, and the protruding portion is formed along an edge of the opening.
