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; a core formed as a structure for maintaining a certain shape and disposed at an inner side of the envelope to support the envelope; and a filler formed as powder having micro pores and filled at the inner side of the envelope. The use of a glass fiber core can be avoided, an internal vacuum degree can be easily maintained, and a life span can be lengthened.
