The objective of the invention is to obtain a refrigerator capable of preventing an inner cubage and having excellent energy-saving performance. The refrigerator comprises: a freezing temperature chamber arranged in an insulating box; a first refrigerating temperature chamber arranged on the freezing temperature chamber; a second refrigerating temperature chamber arranged under the freezing temperature chamber; and a cooler chamber arranged behind the freezing temperature chamber and provided with a cooler; the refrigerator is characterized by comprising a first cold air duct for guiding return cold air from the first refrigerating temperature chamber to the second refrigerating temperature chamber; a second cold air duct for guiding return cold air from the second refrigerating temperature chamber to the lower side of the cooler chamber; a width of a first opening of the second cold air duct communicated to the cooler chamber is basically equal to the width of the cooler, and the return cold air from the sec
