Used is a method for producing a thermal insulation sheet, including: composite-forming including impregnating a nonwoven fabric with a basic sol prepared by adding a carbonate ester to a water glass composition to form a hydrogel-nonwoven fabric composite; surface-modifying including mixing the composite with a silylating agent for surface modification; and drying including removing liquid contained in the composite through drying at a temperature lower than the critical temperature of the liquid under a pressure lower than the critical pressure of the liquid. Used is a thermal insulation sheet including an aerogel and a nonwoven fabric, where the thermal insulation sheet exhibits a compressibility of 40% or lower at 0.30 to 5.0 MPa.

Thermal insulation sheet and method for producing the same, and electronic device and battery unit

An object is to provide a heat insulating sheet that is easily attachable even if a size is increased, and to provide a method for manufacturing the same. A heat insulating sheet includes nonwoven fabric, and heat insulating body carrying xerogel in a space inside nonwoven fabric. Heat insulating body includes first region carrying the xerogel, and second region not carrying the xerogel and provided inside an outer periphery of heat insulating body. The heat insulating sheet is configured such that each of both surfaces of heat insulating body is provided with protective sheet, and in a periphery of heat insulating body and in second region, protective sheets are mutually joined or protective sheets and second region are joined.
