Abstract:
The present invention addresses the problem of providing a heat-insulating sheet having exceptional heat insulation performance by using a paper-based ingredient in at least part of the heat-insulation sheet. This heat-insulating sheet comprises: a first sheet having a plurality of protrusions on one side, the first sheet being formed from a paper-based ingredient having fibers; and a second sheet that faces toward the protrusions of the first sheet. At least some of the protrusions have a proximal end section and a low-density section having a lower fiber density than the proximal end section, the fiber density being defined as the density of the fibers constituting the paper-based ingredient.
