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 first 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 conductive resistance sheet having a first end connected to at least one of the first plate and the second plate, the conductive resistance sheet configured to resist heat transfer between the second space and the first space;
a shield provided adjacent to the conductive resistance sheet; and
a gasket provided to the shield, wherein
a first surface of the conductive resistance sheet is heat-insulated by the shield provided adjacent to the conductive resistance sheet,
a second surface of the conductive resistance sheet is heat-insulated by the third space, and
wherein a side frame is provided between the conductive resistance sheet and the second plate, and the side frame is to provide at least one portion of the wall and to define part of the third space,
wherein the side frame includes a first portion connected to a second end of the conductive resistance sheet, a second portion connected to the second plate, and a bent portion connected between the first portion and the second portion,
wherein the bent portion includes a first surface to face the third space, and a second surface to face the shield.
