Abstract
Disclosed are a vacuum insulation member, a refrigerator having a vacuum insulation member, and a method for fabricating a vacuum insulation member. The vacuum insulation member includes: an envelope having gas impermeability and having a certain decompressed space therein; and a core having a certain shape, having an empty space formed therein, and disposed at an inner side of the envelope to support the envelope. The use of a glass fiber core can be avoided, and thus, employing equipment for preprocessing the glass fiber core and time required therefor can be restrained and fabrication can be facilitated.
