Abstract: A decrease in the detection accuracy of infrared rays is suppressed. Vehicle glass includes a light shielding region in which a far-infrared ray transmitting region is formed, the far-infrared ray transmitting region including an opening and a far-infrared ray transmitting member (20) disposed in the opening. In the far-infrared ray transmitting member (20), the average transmittance of far-infrared rays having wavelengths of 8 μm to 13 μm at a first position (P1) in a case where the far-infrared rays are emitted in a direction perpendicular to a surface (20a) on a vehicle exterior side is different from the average transmittance of the far-infrared rays having wavelengths of 8 μm to 13 μm at a second position (P2) that is lower than the first position (P1) in the vertical direction in a case where the vehicle glass is mounted to a vehicle.

Abstract: To appropriately transmit far-infrared rays while ensuring design. A far-infrared ray transmission member (20) includes a base material (30) configured to transmit far-infrared rays, and a functional film (31) formed on the base material (30). Dispersion of reflectances with respect to pieces of light at a wavelength of 360 nm to 830 nm in increments of 1 nm is equal to or smaller than 30, a reflectance with respect to visible light defined by JIS R3106 is equal to or lower than 25%, and an average transmittance with respect to light at a wavelength of 8 μm to 12 μm is equal to or higher than 50%.
