Abstract: A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate, and a heat resistance unit comprising at least one radiation resistance sheet that blocks radiation heat transfer in the vacuum space so as to reduce heat transfer between the first plate and the second plate. The support includes two support plates, and the at least one radiation resistance sheet is supported by at least one support protrusion provided on a bar, which couples the two support plates to each other, to maintain an interval between the first plate and the second plate.

Abstract: A vacuum adiabatic body includes a first plate configured to define at least a portion of a wall for a first space, a second plate configured to define at least a portion of a wall for a second space having a temperature different from that of the first space, and a support configured to maintain the third space. The support includes a coupling mechanism by which a first support plate and a second support plate are coupled to each other and integrated with each other and a seating mechanism configured to maintain a gap between the first support plate and the second support plate at points at which the first support plate and the second support plate contact each other. The seating mechanisms are spaced apart from the coupling mechanism.
