To provide laminated glass excellent in the quality and the cost, in which two glass plates differing in the plate thickness can easily be bent with good accuracy. Laminated glass 60 comprising a plurality of glass plates 12 and 14 bent into a predetermined shape, and an interlayer 40 interposed between the plurality of glass plates 12 and 14, at least two glass plates 12 and 14 among the plurality of glass plates 12 and 14 differing in the plate thickness, wherein the two glass plates 12 and 14 differing in the plate thickness have different glass compositions, and at an optional temperature between the annealing point and the softening point of the thick glass plate 12, the thick glass plate 12 has a lower viscosity than the thin glass plate 14.
