Abstract:
With heat insulating materials configured by alternately laminating metal vapor deposition sheets with nets, it was difficult to satisfy heat insulation property requirements while reducing the weight of the material. A heat insulating sheet according to the present invention is provided with: a first heat conduction-limiting layer for limiting heat conduction; a first radiant heat-reflecting layer, which is disposed on one surface of the first heat conduction-limiting layer and is for reflecting radiant heat; and protrusions, which comprise resin at least on the surface and protrude from the surface of the first radiant heat-reflecting layer opposite to the surface on which the first heat conduction-limiting layer is laminated.
