。 a refrigerator having an elongated cylindrical cold finger that generates cryogenic temperature at the tip; an infrared detecting element attached to the tip of the cold finger and used by cooling it to a cryogenic temperature; and the cold finger and the infrared ray. an outer shell that surrounds the detection element and vacuum insulates the cold finger and the infrared detection element; a window attached to the outer shell that transmits infrared rays; and infrared rays other than those that pass through the window. In an infrared detection device comprising a cold finger that covers the side of the infrared detection element to prevent the infrared light from entering the detection element, the cold finger has a temperature gradient from a tip to a base ranging from an extremely low temperature to room temperature. an infrared detection device, wherein the cold shield is attached near the center of the cold finger, where the temperature thereof is intermediate between a cryogenic temperature and a room temperature.
