Abstract: A heat insulating sheet includes, a first sheet, a first heat insulator disposed on a main surface of the first sheet and including a first xerogel, a second heat insulator disposed on the main surface of the first sheet apart from the first heat insulator and including a second xerogel, and a second sheet disposed on the main surface of the first sheet to cover the first and second heat insulators. A first region of the heat insulating sheet provided between the first and second heat insulators viewing in a direction perpendicular to the main surface has an extensible rate larger than an extensible rate of each of the first and second heat insulators. The heat insulating property of this heat insulating sheet hardly degrades.

Abstract: A composite sheet includes a thermally-conductive sheet, a first insulating sheet that covers one surface of the thermally-conductive sheet, and a second insulating sheet that covers another surface of the thermally-conductive sheet, and seals the thermally-conductive sheet between the first and second insulating sheets. The thermally-conductive sheet has a first through hole provided therein. The composite sheet has an insulating lamination portion at which the first insulating sheet is stacked on the second insulating sheet to seal an inner wall surface of the first through hole. The insulating lamination portion has a second through hole provided inside the first through hole and having a hole diameter which is smaller than a hole diameter of the first through hole.

Abstract: The present disclosure is intended to provide a thermal insulation sheet that is resistant to being damaged even if enlarged in shape, as well as a multilayer thermal insulation sheet including such a thermal insulation sheet. The thermal insulation sheet includes a thermal insulator made of a nonwoven fabric that supports a xerogel in internal spaces. The thermal insulator has a plurality of through holes in an internal region in a plan view. Protective sheets are disposed on two respective surfaces of the thermal insulator. The protective sheets are joined together at a periphery of the thermal insulator and through inside the through holes.

Abstract: An object of the present disclosure is to provide a heat conducting sheet that can be easily positioned and can absorb unevenness of a heat generating component and a heat radiating component to reduce thermal resistance, and an electronic device using the same. Heat conducting sheet includes rectangular graphite sheet and attachment sheet that covers graphite sheet, graphite sheet being exposed at least two opposite sides. Graphite sheet is exposed from between attachment sheets, a thickness of attachment sheet is made thinner than (T0-T1) where an initial thickness of graphite sheet is T0, and a thickness when a pressure of 100 kPa is applied to the graphite sheet is T1.
