Abstract

An automobile window glass includes a glass substrate, a black ceramic layer and a water absorbing antifogging film. The black ceramic layer is formed in a peripheral portion on a vehicle-interior side main surface of the glass substrate. The water absorbing antifogging film is formed on the vehicle-interior side main surface of the glass substrate and is located in an inner peripheral side relative to the peripheral portion. A space of more than 1 mm and less than 30 mm exists between the black ceramic layer and the water absorbing antifogging film on the vehicle-interior side main surface of the glass substrate.

Claims
