Abstract

A vacuum adiabatic body includes: a first plate member; a second plate member; a sealing part sealing the first plate member and the second plate member to provide a third space; a supporting unit maintaining the third space; a heat resistance unit for decreasing a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted. The vacuum adiabatic body further includes a peripheral adiabatic part provided to an outer wall of an edge portion of the third space to improve the adiabatic performance of the edge portion of the third space, and the peripheral adiabatic part is provided as a separate adiabatic member. Accordingly, an adiabatic effect may be improved and volume of an outer door in a door-in-door refrigerator may be increased.
