Summary:Provided is an infrared transmitting member that comprises an appropriate antireflective film. The infrared transmitting member 1 has an average transmittance of 30% of infrared rays having a wavelength of 8-15 µm, and has a substrate 10, and an organic film 12 that is formed on at least one surface of the substrate 10 and that has a thickness of 0.5-3 µm. The organic film 12 includes carbon atoms and nitrogen atoms, and the ratio of the content of nitrogen atoms to the content of carbon atoms is greater than 0.04 in terms of molar ratio. L'invention concerne un élément de transmission infrarouge qui comprend un film antireflet approprié. L'élément de transmission infrarouge 1 présente une transmittance moyenne de 30 % de rayons infrarouges ayant une longueur d'onde de 8 à 15 µm, et comporte un substrat 10, et un film organique 12 qui est formé sur au moins une surface du substrat 10 et qui présente une épaisseur de 0,5 à 3 µm. Le film organique 12 comprend des atomes de carbone et des atomes d'azote, et le rapport entre la teneur en atomes d'azote et la teneur en atomes de carbone est supérieur à 0,04 en termes de rapport molaire. 適切な反射防止膜を備えた赤外線透過部材を提供する。赤外線透過部材1は、波長が8μm以上15μm以下の赤外線の平均透過率が30%以上である赤外線透過部材であって、基材10と、基材10の少なくとも一方の表面に形成されて厚さが0.5μm以上3μm以下の有機膜12と、を有する。有機膜12は、炭素原子及び窒素原子を含み、炭素原子の含有量に対する窒素原子の含有量の比率が、モル比で、0.04より大きい。
