<p><P>PROBLEM TO BE SOLVED: To provide a heat insulating member for a vacuum heat insulating material which is further light and decreased in the powder-likeness of a surface as it has sufficient pressure tightness, maintains flexibility which a fiber has, and furthermore can be comparatively easily manufactured. <P>SOLUTION: The heat insulating member 6 is formed of fibers filled in a container or a bag and used in an evacuated state, and constituted such that solidified parts 1, in each of which an intersection between fibers is bound for solidification are formed approximately on the entire surface of the heat insulating member 6 brought into a contact with the wall of the container or the bag, and the internal part of the heat insulating member 6 further inside the surface forms a soft part 2 where there is no binding or relatively less binding. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
