Abstract: A thermal insulation sheet includes a heat storage sheet, an insulation sheet affixed to the heat storage sheet, and a highly-thermoconductive sheet affixed to the insulation sheet. The heat storage sheet contains a resin and powdery microcapsules mixed with the resin. The powdery microcapsules encapsulate latent-heat storage agent. The heat storage sheet has a void ratio not less than 10% and not more than 30%. Or, the heat storage sheet may have surface roughness Ra not less than 2 μm and not more than 20 μm. The thermal insulation sheet suppresses or retards transferring of heat generated in a heat-generating component to outside, and suppresses a rapid rising of a temperature of the heat-generating component.

Abstract: A heat-dissipating sheet includes a thermally-conductive resin sheet, an adhesive layer on an upper surface of the thermally-conductive resin sheet, and a thermally-conductive film on an upper surface of the adhesive layer. The thermally-conductive film has a higher thermal conductivity than the thermally-conductive resin sheet. The thermally-conductive resin sheet has a thin portion that is locally thin to form a recess in a lower surface of the thermally-conductive resin sheet. The recess may be an aperture passing through the thermally-conductive resin sheet. The adhesive layer is exposed from the aperture.

Abstract: A heat-conductive sheet includes a laminated sheet and first and insulating sheets bonded to first and second main surfaces of the laminated sheet. The laminated sheet includes graphite sheets and one or more adhesive layers disposed alternately on the graphite sheets to bonds the graphite sheets to each other. The first insulating sheet is bonded to the second insulating sheet outside an outer circumferential edge of the laminated sheet to seal the laminated sheet between the first and second insulating sheets. The laminated sheet includes an outer circumferential portion connected to the outer circumferential edge and an inner portion apart from the outer circumferential edge. The outer circumferential portion of the laminated sheet has a thickness smaller than a thickness of the inner portion. The heat-conductive sheet has high reliability of sealing the insulating sheet.
