Abstract

A vacuum adiabatic body according to an embodiment may include a first plate, a second plate, and a seal that seals a gap between the first plate and the second plate. Optionally, the vacuum adiabatic body according to an embodiment may include a support that maintains a vacuum space. Optionally, the vacuum adiabatic body according to an embodiment may include a heat transfer resistor that reduces an amount of heat transfer between the first plate and the second plate. Optionally, the vacuum adiabatic body may include a component coupling portion connected to at least one of the first or second plate so that a component is coupled thereto. Optionally, to reduce dew formation, a side plate may have an extension portion extending outwardly of the vacuum space. Accordingly, the vacuum adiabatic body may be improved in productivity.
