Abstract:
There is provided a vehicle glass that appropriately transmits far-infrared rays and has shock resistance. A vehicle glass (1) includes a glass member (10) in which an opening (19) penetrating the glass member (10) from a surface on a vehicle exterior side to a surface on a vehicle interior side is formed and a transmissive member (20) that is disposed in the opening (19), and has an average internal transmittance of 50% or more for light having a wavelength of 8 μm to 13 μm. A ratio Sa/Sb of fracture velocity Sa [km/h] measured on a surface on the vehicle of the transmissive member (20) by a chart stone chipping test and fracture velocity Sb [km/h] measured on the surface on the vehicle exterior side of the glass member (10) is 0.7 or more.
