Abstract: A fiber sheet having first and second surfaces and spaces therein is prepared. The spaces of the fiber sheet are impregnated with silica sol containing water glass and ethylene carbonate. Silica gel is formed by causing the silica sol with which the spaces of the fiber sheet is impregnated to gel while a difference between respective temperatures at the first and surfaces of the fiber sheet is equal to or larger than 50° C. The silica gel is hydrophobized, thereby providing a thermal insulation sheet. In the thermal insulation sheet, compressibilities of the first and second surfaces for a predetermined pressure applied thereto are different from each other. The thermal insulation sheet may be disposed between two battery cells so as to prevent one sell from influencing the other even if the one expands.

Abstract: An object of the present invention is to provide a thermal insulator which is easily position-adjusted when disposed in equipment. A plurality of projections are provided on at least one surface of thermal insulator including nonwoven fabric and xerogel in interior spaces of nonwoven fabric. With this configuration, fine positioning or the like is easily performed when thermal insulator is disposed, and a thickness increases by a height of projections, so that a thermal insulation effect can be improved. Thus, the thermal insulator can be used for thermal insulation of various types of equipment.

Abstract: A heat insulation sheet includes a fiber sheet having spaces therein and a silica xerogel held in the spaces of the fiber sheet. The heat insulation sheet includes a thick region and a low compressible region thinner than the thick region. A compressibility of the low compressible region is equal to smaller than 5% upon having a pressure of 0.7 MPa applied to the low compressible region. This heat insulation sheet is superior in electrical insulation properties and thermal insulation properties, and secures a predetermined distance even in a case that the heat insulation sheet receives pressures from the both sides thereof, thus providing equipment with reliability.
