    Abstract: A laminate with excellent sound insulating properties and bending strength and a laminated glass using the laminate are provided. The laminate contains a layer A and a plurality of layers B. The layer A includes a composition, which contains a resin having a peak at which a tan δ as measured by conducting a complex shear viscosity test under a condition at a frequency of 1 Hz in accordance with JIS K 7244-10 is maximum at −40 to 30° C. The layer A is laminated between at least two of the layers B, in which a shear storage modulus at a temperature of 25° C. as measured by conducting a complex shear viscosity test under a condition at a frequency of 1 Hz in accordance with JIS K 7244-10 is 1.30 MPa or more.

    Abstract: An object is to provide a polyvinyl acetal film which has excellent transparency and can suppress a thermal cracking phenomenon.The above object is achieved by providing a polyvinyl acetal film in which a ratio between a composite modulus (GPa) of the highest part in a convex part and a composite modulus (GPa) of the lowest part in a concave part on a surface of a film on a side in contact with glass, calculated by a nanoindentation measurement using a scanning probe microscope, is 0.90 or less, when a laminated glass is formed. In addition, the above object is achieved by providing a polyvinyl acetal film in which a ratio between a hardness (GPa) of the highest part in the convex part and a hardness (GPa) of the lowest part in the concave part, calculated by the SPM nanoindentation measurement, is 0.90 or less.
