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, a tube passing through at least one of the first plate or the second plate may be provided. Optionally, the tube may be provided as a tube having a predetermined shape. Optionally, a filter metal provided on a bonding surface between the tube and the plate may be provided. Accordingly, the vacuum adiabatic body may be improved in productivity.
