摘要： A laminated glass production method includes bending multiple glass plates into a desired shape by heating the glass plates to near a softening point, stacking the bent glass plates in layers with an interlayer interposed therebetween, and forming laminated glass by bonding the glass plates and the interlayer stacked in layers by applying pressure. At least two of the glass plates composing the laminated glass have different thicknesses. Of the two glass plates having different thicknesses, the thicker glass plate has a lower viscosity than the thinner glass plates at a temperature between the annealing point and the softening point of the thicker glass plate. Forming the laminated glass includes forming an uneven temperature distribution on a principal surface of each of the glass plates.
