Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a first plate configured to define at least a portion of a wall for a first space, a second plate configured to define at least a portion of a wall for a second space having a temperature different from that of the first space, a seal configured to seal the first plate and the second plate so as to provide a third space that has a temperature between a temperature of the first space and a temperature of the second space and is in a vacuum state, and a support configured to maintain the third space. Therefore, the vacuum adiabatic module that is thermally insulated with the vacuum, independently applied at various places, and conveniently used may be realized.
