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 may further include a side plate extending in a height direction of the 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 hinge shaft installed to extend in a depth direction (Z-axis) of the vacuum space from the outside of the vacuum space may be provided. Optionally, at least one of the plate or the support may have a member in which an extension line of a component extending in a height direction (y-axis) of the vacuum space does not pass through the hinge shaft. Accordingly, the vacuum adiabatic body may be improved in productivity.
