Abstract: A heat insulator is disclosed which simplifies processes of measures for preventing contamination of a surrounding caused by falling off of a silica aerogel in a silica-aerogel support heat insulator. In the silica-aerogel support heat insulator, a support layer whose melting point is lower than a melting point of a fiber supporting the silica aerogel is used, and by performing thermal-pressure bonding at a temperature lower than the melting point of the fiber but higher than the melting point of the support layer to cause the support layer to enter the fiber to combine the support layer and the fiber. Thus, processes of measures for preventing contamination of a surrounding caused by falling off of the silica aerogel can be simplified, and use in a large size and/or in a complicated shape is made possible.
