1. A vacuum adiabatic body comprising:
- a first plate defining at least one portion of a first side of a wall adjacent to a first space having a first temperature;
a second plate defining at least one portion of a second side of the wall adjacent to a second space having a second temperature different from the first temperature, the second side of the wall being nearer to the second space than the first side of the wall;
a seal that seals the first plate and the second plate to provide a third space that has a third temperature between the first temperature and the second temperature and is in a vacuum state;
a support that supports the first and second plates and is provided in the third space;
an exhaust port through which a gas in the third space is exhausted;
a conductive resistance sheet having a first end connected to the first plate, the conductive resistance sheet configured to resist heat transfer between the second plate and the first plate; and
a gasket that heat-insulates the conductive resistance sheet, whereina first surface of the conductive resistance sheet is heat-insulated by a shield provided adjacent to the conductive resistance sheet, anda second surface of the conductive resistance sheet is heat-insulated by the third space.
