1. A vacuum adiabatic body comprising:
a first plate;
a second plate;
a vacuum space provided between the first plate and the second plate, the vacuum space to be provided in a vacuum state, wherein the vacuum space has a thickness in a first direction between the second plate and the first plate;
a support provided in the vacuum space to support the first and second plates, the support being disposed next to or adjacent to the first plate;
a side frame provided between the first plate and the second plate to form a gap that extends in the first direction between the second plate and the first plate; and
a sheet to decrease a heat transfer amount thereat, the sheet having a first portion connected with the first plate or the side frame,
wherein the sheet includes:
the first portion mounted on the first plate or the side frame; and
a second portion formed in a shape depressed toward the vacuum space,
wherein the second portion includes:
a first part to be depressed toward the vacuum space; and
a second part to extend from the first part to the first portion,
wherein a coupling part for fixing the sheet to either the first plate or the side frame is provided to the first portion, and the coupling part is spaced apart from a boundary part which is provided between the first portion and the second part.
