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: Provided is a thermal conduction sheet that is easily attached from one face to the other face of a battery cell, the faces being perpendicular to each other. Thermal conduction sheet includes graphite sheet, and insulating sheets between and with which graphite sheet is entirely sandwiched and sealed. Graphite sheet has a plurality of cut-out portions arranged linearly. Thermal conduction sheet is bent at a region where cut-out portions are formed. Thus, thermal conduction sheet is attached from one face to the other face of a battery cell, the faces being perpendicular to each other.

Abstract: 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.

Abstract: A heat-conductive sheet includes first and second insulating sheets placed on each other and a graphite sheet disposed between the first and second insulating sheets. The graphite sheet is entirely sealed by the first and second insulating sheets. The graphite sheet has a first slit provided therein. The first and second insulating sheets have a second slit passing through the first and second insulating sheets. The second slit is located inside the first slit of the graphite sheet.

Abstract: A reactor device includes a coil, a magnetic core having the coil thereon, a case accommodating the coil and the magnetic core, a cooling plate fixed to the case, an insulating sheet disposed between the coil and the cooling plate, a compressible graphite sheet disposed between the coil and the cooling plate, and a screw to fix the cooling plate to the case. The case has a screw hole and an opening provided therein. The screw passes through the screw hole to fix the cooling plate to the case. The coil contacts the insulating sheet through the opening of the case. The graphite sheet contacts the cooling plate. The reactor has high cooling performance and reliability.
