PURPOSE:To prevent the movement of seal layers even in the case of receiving fluctuant external force. CONSTITUTION:Plural plate glass 1, 2 are laminated in the state of being spaced in the thickness direction by a spacer 3 over the whole periphery, and seal layers 4, 5 are interposed between the plate glass 1, 2 and the spacer 3 so as to form a closed space A between plural plate glass 1, 2. In such a double- layered glass, the spacer 3 is formed of an elastic body moderating external force applied to the thickness direction of the plate glass 1, 2, or the seal layer is formed of sealant with reinforcing core material embedded in sealing material. |
