Abstract: Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a mullion configured to divide a space within the refrigerator into a refrigerating compartment and a freezing compartment, an ice maker placed in the freezing compartment, and an ice-making cool air passage passing through the mullion to connect the freezing compartment to the ice maker. Therefore, cool air may be supplied in an adiabatic state to the ice maker disposed in the refrigerating compartment.
