1. A vacuum adiabatic body comprising:
a first plate having a predetermined thickness;
a second plate having the predetermined thickness; and
a seal that seals a space between the first plate and the second plate to form a vacuum state;
a plurality of posts extending between the first plate and the second plate, the plurality of posts being arranged in a grid having a predetermined pitch, wherein:
a distance between the first and second plates is greatest at a position corresponding to a position of one of the plurality of posts, and the distance between the first and second plates is smallest at a position that is furthest away from any one of the plurality of posts, and
when the predetermined thickness is T and the predetermined pitch is P, an inequality of T>0.033×P+0.067 is satisfied.
