There is disclosed a refrigerator including an inner case that defines an exterior appearance of a storage space, an outer case spaced apart a predetermined distance from the inner case, a vacuum space provided between the inner case and the outer case, with being maintained vacuum, to insulate the inner case from the outer case, and a porous filter filled in the vacuum space to restrain conductivity generated by gas existent in the vacuum space.
1. A refrigerator comprising: an inner case that defines a storage space;an outer case facing the inner case and spaced apart a distance from the inner case, the outer case and the inner case defining, between the outer case and the inner case, a vacuum space that is maintained at a vacuum pressure and that is configured to insulate the inner case from the outer case;a porous filter that is located in the vacuum space defined between the outer case and the inner case and that is configured to restrain conductivity generated by gas present in the vacuum s...
