Abstract: Provided is a vacuum adiabatic body. The vacuum adiabatic body includes an alternating current line through which AC current flows as a driving source, a direct current line through which direct current flows as a driving source, and a signal line through which a control signal flows as electric lines configured to electrically connect the first space to the second space. Thus, the number of lines passing through the vacuum adiabatic body may be reduced.

Abstract: A vacuum adiabatic body includes: a first plate member; a second plate member; a sealing part sealing the first plate member and the second plate member to provide a third space in a vacuum state; a supporting unit; a heat resistance unit for decreasing a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted. The heat resistance unit includes a conductive resistance sheet capable of resisting heat conduction flowing along a wall for the third space, and a side frame fastened to the conductive resistance sheet to define at least one portion of the wall for the third space. Accordingly, a vacuum adiabatic body may be capable of resisting heat conduction.
