<P>PROBLEM TO BE SOLVED: To provide an infrared lens alignment device capable of accurately performing alignment operation of a lens unit or the like having an infrared lens. Ž<P>SOLUTION: The infrared lens alignment device includes a difference temperature blackbody furnace 2 which has a plane blackbody furnace 21 radiating an infrared ray and a test chart 22 intercepting an infrared ray as a light source. An infrared image is formed by the difference temperature blackbody furnace 2, and picked up an infrared camera 5 through the lens unit 1. An analysis device 6 calculates optical characteristic on the basis of data of the image picked up by the infrared camera 5. An operator performs the alignment operation by moving and rotating a second infrared lens 12 of the lens unit 1 grasped by an alignment pawl 3 on the basis of a result of calculation by the analysis device 6.
