A refrigerator includes a body having a storage space. The body includes an inner case having the storage space, an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case, a vacuum space provided between the inner case and the outer case sealed to maintain a vacuum state for heat insulating between the inner case and the outer case, a supporting portion provided to contact with the outside surface of the inner case and the inside surface of the outer case to maintain a spaced state of the vacuum space, and a dewing preventive unit adjacent to the supporting portion for preventing dewing from taking place at the outer case by suppressing surface temperature drop of the outer case caused by cold conducted from the inner case to the outer case through the supporting portion.
