Abstract: A method for producing laminated glass for automobile windows includes:
heating and bend forming two glass plates; and
bonding together the two bend-formed glass plates via an interlayer film, wherein before the heating and bend forming of the two glass plates, at least one glass plate of the two glass plates that are flat, is conveyed by a conveying unit while either a conveying unit-facing surface of the at least one glass plate or a non-facing surface of the at least one glass plate that is opposite to the conveying unit-facing surface is scratched by the conveying unit, and
in the bonding together of the two bend-formed glass plates via the interlayer film, the scratched surface is disposed such that the scratched surface is situated on a vehicle-interior side upon the laminated glass for automobile windows being attached to an automobile.

Abstract: A laminated glass includes an interlayer between an exterior glass plate and an interior glass plate; an information acquisition area; and a test area A specified in JIS R3212. The information acquisition area is positioned above the test area A. At least a part of a periphery of the information acquisition area is surrounded by a shielding layer formed of a colored ceramic layer. One of the exterior and interior glass plates is thicker at an upper end than at a lower end. Denoting a degree of thickness difference of the information acquisition area by α and a degree of thickness difference of the test area A by β, a ratio α/β is greater than or equal to 1.01, where α or β is the ratio of thicknesses of the exterior and interior glass plates at the center of gravity of the corresponding area.
