Abstract: Provided is a vacuum adiabatic body. To reduce a heat transfer amount between two plates, the vacuum adiabatic body includes: a conductive resistance sheet connecting plate members to each other, an exhaust port through which a gas of a third space is exhausted, and a sealing frame covering a conductive resistance sheet. A virtual line connecting both end portions of the conductive resistance sheet to each other is installed to be obliquely inclined when at least one extension direction of a first plate member or a second plate member is viewed in a horizontal direction.

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.
