Abstract: A vacuum adiabatic body of the present embodiment may include a first plate, a second plate, a seal configured to seal the first plate and the second plate to provide a vacuum space, and a support configured to maintain the vacuum space. Alternatively, the support may include a first support having a first support plate formed in a grid shape, and a plurality of spacer coupling portions configured to protrude from the first support plate. Alternatively, the support may include a second support having a second support plate formed in a grid shape, and a plurality of spacers protruding from the second support plate and coupled to each of the plurality of spacer coupling parts to form a plurality of bars together with the plurality of spacer coupling parts. Alternatively, the support may include a radiation resistance sheet supported by a portion of the plurality of bars and spaced apart from at least one of the first support plate and the second support plate. Alternatively, each of the support plates may include a plurality of through-holes. Alternatively, a plurality of distribution structures generated after injection molding the first and second supports and spaced apart from each other may be provided in some of the plurality of through-holes of each support plate.
