<P>PROBLEM TO BE SOLVED: To provide a laminated glass enabling to provide an appropriate acoustic preventing performance for each portion of the laminated glass according to the positional relationship between the laminated glass and a passenger, and employing an interlayer having functionality. <P>SOLUTION: The interlayer has at least one resin layer imparted with functionality, wherein the thickness of the interlayer at the upper side is from 1.5 to 3 times of the thickness at the lower side, the thickness at the upper side is at least 1.5 mm, the thickness at the lower side is at least 1 mm, the laminated glass has enhanced functionality more selectively in a portion close to a passenger's head (ears), that senses a sound, than other portions, and thus the laminated glass can prevent optical distortion due to the interlayer. <P>COPYRIGHT: (C)2008,JPO&INPIT |
