Abstract: A heat conductor includes a first layer containing a first resin component and first flake graphite fillers each having a basal plane; and a second layer containing a second resin component and second flake graphite fillers each having a basal plane. The heat conductor is a laminate including the first layer and the second layer, an average of first angles in the first layer is 35 degrees or smaller, each of the first angles is an acute angle between the basal plane of a corresponding one of the first flake graphite fillers and a first laminated surface of the laminate, an average of second angles in the second layer ranges from 55 degrees to 90 degrees, and each of the second angles is an acute angle between the basal plane of a corresponding one of the second flake graphite fillers and a second laminated surface of the laminate.

Abstract: A manufacturing method of a heat insulating sheet of the present disclosure includes a composite generating step of impregnating a nonwoven fiber with a basic sol prepared to generate a composite of a hydrogel-nonwoven fiber, the basic sol being prepared by adding carbonate ester to a water glass composition; and a drying step of drying a liquid contained in the composite at a temperature lower than a critical temperature of the liquid and a pressure lower than a critical pressure of the liquid to remove the liquid from the composite. A heat insulating sheet according to the present disclosure includes an aerogel and a nonwoven fiber, and has a compression rate at 0.30 MPa to 5.0 MPa of 40% or less. In an electronic device of the present disclosure, the heat insulating sheet is disposed between an electronic component and a housing. In a battery unit of the present disclosure, the heat insulating sheet is disposed between batteries. This provides a heat insulating sheet that can be used under a high load and a manufacturing method thereof, and an electronic device and a battery unit including the same.
