PROBLEM TO BE SOLVED: To provide a refrigerator of excellent energy saving performance, capable of restraining an inner volume from being reduced. SOLUTION: This refrigerator includes a freezing temperature zone chamber provided in an insulated box body, the first refrigerating temperature zone chamber provided in an upper side of the freezing temperature zone chamber, the second refrigerating temperature zone chamber provided in an under side of the freezing temperature zone chamber, and a cooler chamber provided in a rear side of the freezing temperature zone chamber, and installed with a cooler, and the refrigerator further includes the first cold air passage for guiding return cold air from the first refrigerating temperature zone chamber to the second refrigerating temperature zone chamber, and the second cold air passage for guiding return cold air from the second refrigerating temperature zone chamber to a lower part of the cooler chamber, a width of the first opening communicated with the cooler chamber of the second cold air passage is substantially same to a width of the cooler chamber, and the return cold air from the second refrigerating temperature zone chamber is made to flow from an under side toward an upper side over the width direction full range of the cooler.
