Abstract
Official abstract text for this publication.
It is an object of the present invention to provide an interlayer film for a laminated glass excellent in a sound-insulating property, which is preferably usable for a head up display and the like wherein a driver can look at the front view and an instrument display simultaneously without requiring to look down, and to provide a laminated glass. The present invention is directed to interlayer film for a laminated glass, which comprises at least a pair of protection layers and a sound-insulating layer sandwiched between the pair of the protection layers, and which has a wedge shape as a cross-sectional shape, a wedge angle θ of 0.1 to 0.7 mrad, the maximum thickness of 2000 μm or thinner, and the minimum thickness of 400 μm or thicker, the minimum thickness of the sound-insulating layer being 20 μm or thicker.
