PURPOSE: A sensor housing unit of an integrated ultralow temperature infrared sensor is provided to enhance productivity by forming the sensor housing unit and the sensor into a body where a leakage test is not necessary. CONSTITUTION: A sensor housing unit of an integrated ultralow temperature infrared sensor comprises a body unit(110), a shaft unit(120), and a flange unit(130). A stepped space unit is formed inside the body unit. The shaft unit is connected to the body unit to be integrated. The flange unit is formed on an end portion of the shaft unit to be integrated and has a diameter larger than that of the shaft unit. The body unit includes a first blade portion and a second blade portion. The first blade portion is extended outwardly to a radial direction in an area adjacent to the shaft unit. The second blade portion is extended in the same direction with the first blade portion by being spaced from the first blade portion.
