PROBLEM TO BE SOLVED: To provide an interlayer film for laminated glass that can increase the rigidity of the laminated glass and that can enhance the acoustic insulation of the laminated glass over a wide range of temperature.SOLUTION: The interlayer film for laminated glass according to the present invention includes a first layer, and a second layer disposed on a first surface side of the first layer, in which the first layer comprises a polyvinyl acetal resin, a second resin component, and a copolymer having a skeleton derived from the polyvinyl acetal resin and a skeleton derived from a third resin component, and the second layer comprises a polyvinyl acetal resin, the loss tangent peak temperature exhibited by the second resin component in the first layer is -30°C or more and 10°C or less, and the loss tangent peak temperature exhibited by the skeleton derived from the third resin component in the copolymer in the first layer is -30°C or more and 10°C or less.SELECTED DRAWING: Figure 1 |
