置。 The infrared detection device is equipped with an infrared detector having a double cylindrical structure in which an infrared detection element is mounted inside, and a cooling device that utilizes the Joule-Thomson effect to cool the infrared detection element to an extremely low temperature. A rod that has the property of deforming when it reaches a certain temperature is installed at the part of the vessel where the jets blowing out from the cooling device collide, and when the temperature of the jets reaches a certain temperature, it deforms and diffuses the jets. An infrared detection device characterized by having a structure.
