1. A refrigerator door comprising:
a vacuum adiabatic body including:
a first plate;
a second plate;
a sheet configured to seal the first plate and the second plate to provide a vacuum space between the first plate and the second plate; and
a support configured to maintain an interval of the vacuum space; and
an outer case configured to contact the second plate and including a metal material, the outer case being thicker than at least a portion of at least one of the first plate or the second plate,
wherein the vacuum adiabatic body includes at least two sections extending in different directions and including a first section and a second section, and
wherein each of the first section and the second section includes the first plate, the second plate and the vacuum space.
