Abstract: To provide improved scratch resistance while transmitting light in a plurality of wavelength ranges. A transmission member (20) includes a base material (30) that transmits far-infrared rays, and a first functional film (32) that is formed on the base material (30). Average transmittance of the transmission member (20) with respect to light at a wavelength from 8 μm to 12 μm is equal to or larger than 50%, and transmittance of the transmission member (20) with respect to light from a laser beam source that emits light in a wavelength range from 0.8 μm to 1.8 μm is equal to or larger than 80%. A refractive index of an outermost layer (34) of the first functional film (32) with respect to light from the laser beam source is equal to or larger than 1.7.

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.
