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.
