1. A vacuum adiabatic body comprising:
a first plate;
a second plate separated from the first plate in a first direction to define a vacuum space between the first plate and the second plate;
a support provided between the first plate and the second plate, wherein the support includes:
a first support plate,
a plurality of couplers protruding from the first support plate,
a second support plate, and
a plurality of spacers protruding from the second support plate and coupled to the plurality of couplers; and
a radiation resistance sheet supported by at least one of the plurality of spacers and spaced apart from at least one of the first support plate or the second support plate,
wherein each of the first and second support plates includes a plurality of through-holes,
wherein the support includes a plurality of distribution structures that are spaced apart from each other and are provided in two or more of the plurality of through-holes of the first and second support plates, and
wherein one of the distribution structures includes a support distribution base located in one of the through-holes.
