ABSTRACT:
A portable information device such as a notebook type computer is provided with a highly efficient thermal insulator capable of blocking transfer of heat between an internal heating component and a device enclosure, so as to reduce temperature rise on a surface of the device. The portable information device is also provided with a highly efficient thermal insulator to block transfer of heat between the heating component and an expansion unit mounting case, thereby reducing temperature rise and preventing malfunction of an external expansion unit. The information device includes the thermal insulator to separate between the internal heating component and the device enclosure, another thermal insulator to separate between the heating component and the expansion unit mounting case, and a heat sink. The thermal insulator is a vacuum thermal insulator including inorganic fiber as a core member.
