Abstract

The present invention relates to a refrigerator having a freezing chamber in a door. The refrigerator includes a case having a door which can be opened/closed, a refrigerating chamber provided on an inside of the case, a freezing chamber (12, 22) provided in a rear of the door (10, 20), a freezing chamber door (90) for opening/closing the freezing chamber (12, 22), and a duct for suppling cold air to the freezing chamber(12, 22), permitting convenient storage in and taking out food of the freezing chamber (12, 22) owing to a large width of the freezing chamber (12, 22).
