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 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 distribution structure provided in one of the through-holes, the distribution structure including a support distribution base located in the through-hole, and
wherein a first distance between adjacent two spacers among the plurality of spacers in the one of the through-holes is longer than a second distance between the support distribution base and a spacer among the adjacent two spacers adjacent to the support distribution base.
