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.
