摘要： Glass (1) for vehicles includes a light blocking region (A2) in which a far-infrared ray transmission region (B) provided with an opening and a far-infrared ray transmission member arranged in the opening, and a visible light transmission region (C) transmitting visible light are formed. The opening is formed between an upper edge part (1a) of the glass (1) and a first position (P1) in a first direction from the upper edge part (1a) toward a lower edge part (1b) of the glass (1), the first position (P1) is a position at which a distance from the upper edge part (1a) is 30% of a length from the upper edge part (1a) to the lower edge part (1b), and between a second position (P2) and a third position (P3) in a second direction from a side edge part (1c) toward a side edge part (1d) of the glass (1) for vehicles. A length (L2a) in the second direction from the second position (P2) to the third position (P3) is 55% of a length (L2) from the side edge part (1c) to the side edge part (1d), and a length of the longest straight line among straight lines connecting optional two points within a surface on a vehicle exterior side is equal to or smaller than 80 mm.

摘要： 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.
