A refrigerator is provided to increase capacitance of an ice storage container by slantingly forming a bottom surface of the ice storage container to reduce an ineffective space of a freezing chamber and a door of the freezing chamber. A refrigerator comprises a body cabinet for forming a storage chamber and a door(4) for opening/closing the storage chamber. An ice making tray(30) is disposed at the door to generate an ice cube. An ice storage container(40) has a bottom portion on which an ice outlet is formed. A bottom surface(41) formed around the ice outlet is inclined with respect to a horizontal surface. The angle of inclination is in a range of 20 to 60 degrees. A bottom surface of the ice storage container is inclined in a lower direction toward the storage chamber.
