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.
