Abstract: An vacuum adiabatic body includes a first plate, a second plate, and a support configured to maintain a vacuum space between the first and second plates. The support includes a support plate supported on an inner surface of one of the first plate and the second plate and a bar extending from the support plate. The bar contacts an inner surface of the other of the first plate and the second plate. The one end of the bar has a cross-section less than that of the other end of the bar.
