1. A vacuum adiabatic body comprising:
a first plate to have a first temperature;
a second plate to have a second temperature different from the first temperature;
a seal configured to seal the first plate and the second plate, and to provide a space that has a third temperature, the space to be provided into a vacuum state;
a porous substance to be disposed within the space;
a film configured to accommodate the porous substance; and
an exhaust port configured to exhaust air from within the space,
wherein the air exhausted through the exhaust port includes air inside of the film.
