Abstract

This invention provides a laminated glass which can suppress air bubble defects around an electroconductive film formed by providing a sound shielding intermediate film comprising three polyvinyl acetal layers, coating an electrocondutive paste and heating the assembly. In one embodiment of the laminated glass, the distance (D1) between the inner side surface of a glass plate (1) with an electrocondutive film (5) formed thereon and a second polyvinyl acetal layer (12) having a high plasticizer content is rendered larger than the distance (D2) between the inner side surface of the other glass plate (2) and the second layer (12). In another embodiment, the end part of the second layer (12)is moved backward from the end part of an intermediate film (3) to remove the second layer (12) from on the area where the electrocondutive film (5) has been formed. Polyvinyl acetal having a lower plasticizer content than the second layer (12) is provided on this area.
