Heat insulation sheet, heat insulating material, method for manufacturing heat insulating sheet, and method for manufacturing heat insulating material

摘要

According to the heat insulating material configured by alternately laminating metal vapor deposition sheets and nets, it is difficult to reduce the weight while satisfying the required heat insulating characteristics. The heat insulating sheet is disposed on one surface side of the first heat conduction suppressing layer for suppressing heat conduction, the first radiant heat reflecting layer for reflecting radiant heat, and the first radiant heat reflecting layer. 1 It is provided with the protrusion part which protrudes from the surface on the opposite side to the surface where a heat conduction suppression layer is laminated | stacked, and contains resin at least on the surface.
