Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a conductive resistance sheet configured to connect the first plate to the second plate so as to reduce a heat transfer amount between the first plate and the second plate and a cover assembly configured to cover the conductive resistance sheet. The cover assembly includes an inner cover configured to protect an inside, an outer cover configured to protect an outside, and a front cover configured to protect a front side. The front cover is thicker than the plate. The protection of the conductive resistance sheet and the improvement of the adiabatic effect may be obtained.
