Abstract

A vacuum adiabatic body between a first space and a second space 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.
