Patent attributes
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.
