Abstract

A vacuum adiabatic body includes: a first plate member defining at least one portion of a wall for a first space; a second plate member defining at least one portion of a wall for a second space having a different temperature from the first space; a sealing part sealing the first plate member and the second plate member to provide a third space that has a temperature between the temperature of the first space and the temperature of the second space and is in a vacuum state; a supporting unit maintaining the third space; a heat resistance unit for decreasing a heat transfer amount between the first plate member and the second plate member; an exhaust port through which a gas in the third space is exhausted; a side frame provided at an edge portion of the third space, the side frame having at least one portion defining a wall for the third space; and a peripheral frame fixed to the side frame to have a part mounted thereto. Accordingly, each part of the vacuum adiabatic body can be mounted without any interference, and an adiabatic effect can be improved.
