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.
