    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.

    Abstract: A heat insulating material is a sheet including a fiber and an aerogel. The fiber is aligned in a certain direction in the sheet. A heat insulating structure is used that includes: a high-temperature unit; a low-temperature; and the heat insulating material joining the high-temperature unit and the low-temperature to each other. The certain direction of the heat insulating material is a direction in which the high-temperature unit and the low-temperature unit are joined to each other. A heat insulating structure is used that includes: a first battery cell; a second battery cell; the heat insulating material disposed between the first battery cell and the second battery cell; and a cooling plate that is in contact with the first battery cell, the second battery cell, and the heat insulating material.
