Abstract
A vacuum adiabatic body and a refrigerator having the vacuum adiabatic body. The vacuum adiabatic body comprises: a first plate, the first plate having a first thickness; a second plate spaced apart from the first plate in an opposite manner, the second plate having a second thickness, and the first thickness being greater than the second thickness; and sealing members arranged between the first plate and the second plate and configured to seal and fix the first plate and the second plate, a vacuum cavity being defined among the first plate, the second plate, and the sealing members. According to the vacuum adiabatic body, convection heat transfer can be reduced by vacuumizing between two plates which are sealingly connected; and the whole vacuum insulation body is stable in structure and not too heavy.
