To provide an infrared transmission product capable of preventing red light from being seen through the main body.SOLUTION: A cover 10 includes a main body 11 covers both an infrared irradiation part 91 and an infrared light receiving part 92 in an infrared camera device 90, which has infrared transparency. The main body 11 includes: a substrate 20 that absorbs visible light; and a red light absorption layer 30 that suppresses transmission of red light with a wavelength of 700 nm to 900 nm, which is formed over the rear surface of the base material 20 in the traveling direction of the infrared rays from the irradiation unit 91.SELECTED DRAWING: Figure 4 【課題】本体部を通じて赤色光が視認されることを抑制することができる。【解決手段】カバー１０は、赤外線カメラ装置９０における赤外線の照射部９１及び受光部９２の双方を覆うとともに赤外線の透過性を有する本体部１１を備える。本体部１１は、可視光を吸収する基材２０と、照射部９１からの赤外線の進行方向における基材２０の後面に設けられ、７００ｎｍ～９００ｎｍの波長の赤色光の透過を抑制する赤色光吸収層３０とを備える。【選択図】図４
