PURPOSE: To obtain safety glass effectively shielding heat ray without dropping a visible light transmittance, producible without changing the conventional production process of safety glass, by laying a non-rigid resin layer containing a heat ray shielding metal oxide between a pair of glass plates.

CONSTITUTION: In safety glass comprising a pair of glass plates and a non-rigid resin layer laid between a pair of glass plates, a heat ray shielding metal oxide is added to the non-rigid resin layer. SnO2 or In2O3 having ≥0.lμm particle diameter is especially suitable as the heat ray shielding metal. The reason why the particle diameter is 0.1μm is that the scattering and absorption of visible light are enlarged and transparency can not be obtained when the particle diameter exceed 0.1μm. It is known that the light scattering by particles is maximized when the particle diameter is a size of 1/2 wavelength and is proportional to the sixth power of particle diameter in the region smaller than it.
