1. A vacuum adiabatic body comprising:
a first plate configured to define at least a portion of a wall for a first space;
a second plate comprising an outer flat portion configured to define at least a portion of a wall for a second space;
a seal configured to seal between the first plate and the second plate so as to provide a third space, and the third space to be in a vacuum state; and
a support configured to maintain the third space;
wherein the first plate comprises:
an inner flat portion configured to define at least a portion of the wall for the first space;
a first extension portion to extend in a first direction from an edge of the inner flat portion toward the second space, the first extension portion providing a thickness portion of the third space; and
a second extension portion to extend from an edge of the first extension portion in a second direction transverse to the first direction,
wherein the second extension portion contacts the outer flat portion of the second plate, and the seal is provided on a contact surface between the second extension portion and the outer flat portion,
wherein the second plate further comprises an edge extension portion that extends from an edge of the outer flat portion in a third direction opposite to the first direction, the seal being disposed between the edge extension portion and the first extension portion, and
wherein a length of the edge extension portion of the second plate in the third direction is less than a length of the first extension portion of the first plate in the first direction.
