A refrigerator comprising: a vacuum adiabatic body configured to have an accommodation space for accommodating a product; and a door configured to selectively open the accommodation space; wherein the vacuum adiabatic body includes: a first plate member configured to define at least a portion of a wall for space inside the refrigerator, the first plate member being made of a material having a high thermal conductivity coefficient; a second plate member configured to define at least a portion of a wall for space outside the refrigerator having a different temperature from the space inside the refrigerator; a sealing part configured to seal the first plate member and the second plate member so as to provide a vacuum space part which has a temperature between the temperature of the space inside the refrigerator and the temperature of the space outside the refrigerator, the vacuum space part being a space in a vacuum state; a supporting unit configured to maintain the vacuum space part; and a conductive resistance sheet configured to connect the first plate member and the second plate member with each other so as to reduce heat transfer amount between the first plate member and the second plate member, and characterized in that: the vacuum adiabatic body further includes: a perforation plate in which a cool air supply gap part through which cool air flows at a gap between the first plate member and the perforation plate is provided, the perforation plate providing at least two holes for discharging cool air into the space inside the refrigerator; and wherein the first plate member is made of metal and the perforation plate is made of resin. a vacuum adiabatic body configured to have an accommodation space for accommodating a product; and a door configured to selectively open the accommodation space;
