PURPOSE: A cooled infrared detector and a manufacturing method thereof are provided to simultaneously detect a short wavelength band of infrared ray and effectively perform process stabilization and signal processing through miniaturization and simplification of missile. CONSTITUTION: A metal housing has a can shape. An epoxy housing is surrounded by the inner side of the metal housing. A detecting element is installed on the inner bottom of the metal housing. A medium-wavelength detecting element(610) comprises an infrared window covering the upper surface of the metal housing and the detecting element is installed so that bars gather to form a shape of "+ " . A short-wavelength detecting element(620) has a shape of "x " by gathering of bars and is installed not to match with the medium-wavelength detecting element. Epoxy(630) is filled in the gap between the short-wavelength detecting element and the short-wavelength detecting element.
