<p>A portable information appliance such as notebook computers, provided with a high-performance insulating material able to cut off heat transfer between an internal heating unit and a device's case and restricting a rise in the device surface temperature. A portable information appliance provided with a high-performance insulating material able to cut off heat transfer between a heating unit and an add-on unit attaching case, restricting a rise in external add-on unit temperature, and preventing erroneous operations. This information appliance is provided with an insulating material for cutting off an internal heating unit from a device case, an insulating material for cutting off a heating unit from an add-on unit attaching case, and a radiating sheet, the insulating material being a vacuum insulating material with inorganic fibers used as a core material.</p> |
