A refrigerator comprising: a body having a storage space for storing a predetermined storage object, wherein 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 sealing unit (200, 300) for sealing a front of the vacuum space formed between a front of the inner case and a front of the outer case and reducing a heat transfer rate between the inner case and the outer case, wherein the sealing unit includes: a blocking member (210, 310) arranged in front of the vacuum space connected between a front edge of the inner case and a front edge of the outer case to block the front of the vacuum space; a filling member (220, 320) of an insulating material provided in front of the blocking member (210, 310); and a reinforcing member arranged in front of the filling member for reinforcing strength of the sealing unit, characterized in that the blocking member (210, 310) includes a first coupling portion (211, 311) provided to one side thereof coupled to and supported on the front edge of the inner case and a second coupling portion (212, 312) provided to the other side thereof coupled to and supported on the front edge of the outer case, wherein the blocking member (210, 310) includes a projection provided between the first coupling portion and the second coupling portion projected toward the vacuum space for distributing a pressure caused by a pressure gradient formed between the vacuum space and an outside space, or a recess provided in rear of the blocking member opposite to the vacuum space between the first coupling portion and the second coupling portion for distributing a pressure caused by a pressure gradient formed between the vacuum space and an outside space; wherein the first and second coupling portions (211, 212; 311, 312) include an inside contact surface (211b, 212b) respectively in contact with an inside surface of the front edge of the inner case and of the outer case, and an outside contact surface (211a, 212a) respectively in contact with an outside surface of the front edge of the inner case and of the outer case and a front contact surface (211c, 212c) between the inside contact surface (211b, 212b) and the outside contact surface (211a, 212a) to be in contact respectively with a front end of the inner case and of the outer case. a body having a storage space for storing a predetermined storage object, wherein the body includes;
