Abstract: A refrigerator includes a vacuum adiabatic body having a storage space to store a product and a door to open or close the storage space. The main body includes a first plate and perforation plate. A cool air supply gap through which cool aft flows is formed between the first plate and the perforation plate. At least two holes through which cool air is discharged to the storage space are formed in the perforation plate. The first plate may be a wall of the main body.

Abstract: A vacuum adiabatic body may include: 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; a supporting unit maintaining the third space; a heat resistance unit at least including a conductive resistance sheet capable of resisting heat conduction flowing along a wall for the third space to decrease 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. A side frame may be fastened to the conductive resistance sheet and the second plate member, and the side frame is fastened to an edge portion of the second plate member. Accordingly, the formation of dews may be prevented and an adiabatic effect may be improved.
