Claim 10:
11. A vacuum adiabatic body, comprising:
a first plate having a first thickness;
a second plate having the first thickness;
a seal that seals a space between the first plate and the second plate to form a vacuum state; and
a support having a plurality of posts extending between the first and second plates and 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,
the support is configured such that a solid conduction heat transfer between the first and second plates is greater than a radiation heat transfer between the first and second plates, and a gas conduction heat transfer between the first and second plates is less than the radiation heat transfer, and
the predetermined pitch has a value greater than a value required for a heat conductivity of the space to be 0.002 W/mK regardless of a value of the first thickness to vary.
