<P>PROBLEM TO BE SOLVED: To provide an infrared transmission structure suppressing the transmission of visible light with comparatively simple constitution. Ž<P>SOLUTION: A lens 1 serving as an infrared transmission structure includes a substrate 2 and a visible light shielding layer 3 formed on the main surface of the substrate 2. In this manner, the transmission of visible light in the lens 1 can be suppressed simply by arranging the visible light shielding layer 3 on the surface of the substrate 2. Further, since the visible light shielding layer 3 is formed on the surface of the substrate 2, there is no need to arrange a filter or the like in addition to the lens 1. An infrared detector with the lens 1 is not enlarged due to installation of the filter. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
