PROBLEM TO BE SOLVED: To prevent the transmission color and the reflection color from excessively coloring and increase heat resistance by forming multi-layers on the glass plate surface in turns from the glass plate side, a transparent dielectric film layer in a specific thickness, a layer mainly comprising silver, a transparent dielectric layer, a layer of silver and a transparent dielectric layer. SOLUTION: On the surface of a glass pate 2, a transparent dielectric layer 3 of 5-18nm thicknesss comprising a film mainly comprising zinc oxide, a film mainly comprising tin oxide or their laminated multilayer film and the film 4 of 7-11nm, comprising silver or comprising silver and at least one kind of metal selected from among palladium, gold, indium, zinc, tin, aluminum and copper, a transparent dielectric film layer 3 of 70-85nm thickness, the layer, 4 mainly comprising silver of 11-14nm thickness and a transparent dielectric layer 3 of 25-40nm thickness are laminated in turns to give a heat-insulating glass of transmission color of -3<a*<0, 0<b*<3 shown according to L*a*b* system. |
