1. A vacuum adiabatic body comprising:
a first plate having a first temperature;
a second plate having a second temperature different than the first temperature;
a seal that seals the first plate and the second plate to provide an inner space, the inner space including a main portion and a side portion, and the inner space to be provided in a vacuum state;
a shielding part provided as an adiabatic structure and outside the inner space;
a peripheral frame being mounted in a shape of a closed curve at an outer circumferential portion of the inner space, the shielding part having at least one portion fixed to the peripheral frame;
a side frame including a portion that extends from the first plate toward the second plate and defines at least one portion of a wall for the inner space; and
a conductive resistance sheet provided to reduce heat transfer between the first plate and the second plate,
wherein the shielding part is disposed adjacent to the first plate, the shielding part is disposed on a first side of the first plate, and the inner space and the second plate are disposed on a second side of the first plate, opposite to the first side of the first plate, such that the inner space is between the second plate and the second side of the first plate,
wherein the shielding part is arranged in parallel with the first plate, or the shielding part includes a portion overlapping the first plate in a thickness direction of the inner space,
wherein the shielding part is provided to cover the conductive resistance sheet in order to reduce adiabatic loss caused through an outer surface of the conductive resistance sheet,
wherein the shielding part is fixed or inserted into a gap part provided outside the peripheral frame, and
wherein the gap part is provided between the peripheral frame and at least one of the first plate, the second plate or the side frame.
