PROBLEM TO BE SOLVED: To provide an interlayer for laminate glass excellent in acoustic insulation and used especially suitably for a head-up display or the like capable of seeing both of forward field and instrument display at the same time without lowering a sight line by an operator and a laminate glass.SOLUTION: There is provided an interlayer for laminate glass consisting of at least a pair of protective layers 1 and an acoustic insulation layer 2 sandwiched between the pair of protective layers 1, having a cross section shape with a wedge shape, a wedge angle θ of the cross section of 0.1 o 0.7 mrad, maximum thickness 4 of 2000 μm or less and minimum thickness 5 of 400 μm or more. The interlayer for laminate glass has minimum thickness of the acoustic insulation layer 2 of 20 μm or more.SELECTED DRAWING: Figure 1
