Abstract:
A laminated glass (10) has a structure in which seven sheet glasses (20) and six PVB resin layers (30) are laminated alternately. A laminated region from a transparent surface (10a) on one side to 4.0 mm comprises two 0.7 mm-thick glass layers formed of two sheet glasses (20), one 0.8 mm-thick glass layer formed of the portion (20c) of one 1.5 mm-thick sheet glass (20) positioned in the laminated region, and two adhesion layers (30) with thicknesses of 1.3 mm and 0.5 mm. Each of the adhesion layers is interposed between the glass layers and is adhered to the glass layers. The laminated region with a depth of 4.0 mm from a transparent surface (10b) on the other side also has the same laminated structure as that in the above laminated region.
