An objective of the present invention is to provide a laminate having excellent sound insulation and bending strength, and a laminated glass using said laminate. A further objective of the present invention is to provide a laminate and laminated glass with which a reduction in sound insulation performance in a high frequency region due to a coincidence phenomenon is suppressed, a change in sound insulation properties over time after the production of the laminated glass is reduced, and excellent sound insulation properties in a wide temperature range are achieved. The present invention relates to a laminate that has an A layer, which includes a composition containing a resin having, in the range of -40 to 30 °C, a peak at which tanδ, which is measured by carrying out a complex shear viscosity text in accordance with JIS K 7244-10 under frequency conditions of 1 Hz, is highest, and a plurality of B layers, wherein the A layer is laminated between at least two B layers, and the shear storage modulus at a temperature of 25 °C, said modulus being measured by carrying out a complex shear viscosity test in accordance with JIS K 7244-10 under frequency conditions of 1 Hz, is 1.30 MPa or more. |
