1. A vacuum adiabatic body comprising:
- a first plate that defines at least one portion of a first side of a wall adjacent to a first space having a first temperature;
a second plate that defines at least one portion of a second side opposite the first side of the wall, the second side adjacent to a second space having a second temperature different from the first temperature of the first space;
a seal that seals the first plate and the second plate to provide a third space that has a third temperature between the first temperature of the first space and the second temperature of the second space, the third space being in a vacuum state;
a support that supports the first and second plates and is provided in the third space;
a heat resistance devices that reduces a heat transfer amount between the first plate and the second plate; and
an exhaust port through which a gas in the third space is exhausted,wherein the support includes;
a porous substance; and
a film made of a resin material, the film shaped to accommodate the porous substance therein.

Abstract
A vacuum adiabatic body, a method for fabricating a vacuum adiabatic body, a porous substance package, and a refrigerator including a vacuum adiabatic body and a porous substance package are provided. The vacuum adiabatic body may include a first plate, a second plate, a seal, a support, a heat resistance device, and an exhaust port. The support may include a porous substance and a film made of a resin material, the film configured to accommodate the porous substance therein. Accordingly, it may be possible to provide a vacuum adiabatic body through an inexpensive process.
