    Abstract: Sound leakage is suppressed while far-infrared rays are appropriately transmitted. Vehicle glass 1 includes: a glass member 10 in which an opening portion 19 penetrating from a surface 10A on a vehicle exterior side to a surface 10B on a vehicle interior side is formed; a transmission member 20 that is arranged in the opening portion 19 and transmits far-infrared rays; and a cover portion 30 that covers a surface 20b on the vehicle interior side of the transmission member 20. The cover portion 30 blocks a first space S1 that is on the vehicle interior side compared to the glass member 10 and that includes the surface 20b on the vehicle interior side of the transmission member 20 from a space other than the first space S1 on the vehicle interior side compared to the glass member 10.

    Abstract: A colliding object is suppressed from reaching a driver’s seat, and an occupant and an object in a vehicle compartment are suppressed from being thrown out of a vehicle. In a vehicle glass 1, a far-infrared transmitting region in which an opening portion and a far-infrared transmissive member 20 arranged in the opening portion are provided is formed in a light shielding region. The vehicle glass 1 includes a protective member 40 that is provided on a vehicle interior side of the far-infrared transmissive member 20 and overlaps with at least a part of the far-infrared transmissive member 20 when viewed from a direction orthogonal to a vehicle exterior side surface 20a of the far-infrared transmissive member 20.

    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.

    Abstract: The present invention aims to provide a vehicular exterior member that is excellent in strength and cost, and sufficiently ensures a viewing field of sharpness of a thermal image obtained by a far-infrared camera. A vehicular exterior member that includes a light blocking region and is configured to be attached to a vehicle equipped with a far-infrared camera. The vehicular exterior member further includes, in the light blocking region, a far-infrared ray transmitting region having an opening and a far-infrared ray transmitting member disposed in the opening. An average transmittance of far-infrared rays having a wavelength ranging from 8 to 13 μm of the far-infrared ray transmitting member is equal to or larger than 25%. A length of the longest straight line in straight lines connecting any desired two points on a surface on a vehicle exterior side of the far-infrared ray transmitting member is equal to or smaller than 80 mm. A diameter of the largest circle in circles formed in a projected shape obtained by projecting the far-infrared ray transmitting member in an optical axis direction of the far-infrared camera is equal to or larger than 12 mm. An average thickness of the far-infrared ray transmitting member is equal to or larger than 1.5 mm.
