Abstract: Disclosed are an infrared sensor assembly for precisely detecting a location where a heat source is generated and a refrigerator having the infrared sensor. To this end, comprised are an infrared sensor fixed to a supporting frame for receiving infrared rays generated at the heat source; a case having the infrared sensor mounted therein and an infrared filter mounted at an upper surface thereof, the infrared filter transmits only the infrared rays; and a receiving range limiting means mounted between the infrared sensor and the infrared filter in the case for limiting a range of the infrared rays received into the infrared sensor so as to precisely detect a location of the heat source.
