PROBLEM TO BE SOLVED: To provide a refrigerator capable of keeping freshness of food for a longer period in comparison with a conventional one by efficiently and sufficiently exerting food storage performance by the air of low concentration of oxygen (air of high concentration of nitrogen). SOLUTION: This refrigerator comprises a refrigerator main body divided into a plurality of storage compartments, and an oxygen separating device for separating oxygen in the air, at least one of the storage compartments is a low oxygen storage compartment having a low oxygen state inside by introducing the air of low concentration of oxygen after separation of oxygen, and the low oxygen storage compartment comprises a low oxygen concentration air introduction opening for introducing the air of low oxygen concentration after separation of oxygen, and a discharge opening for discharging the air in the low oxygen storage compartment. The low oxygen concentration air introduction opening and the discharge opening for discharging the air in the low oxygen storage compartment are separated from each other by more than a height dimension in the low oxygen storage compartment.
