INTERMEDIATE FILM FOR LAMINATED GLASS, AND LAMINATED GLASS

There is provided an interlayer film for laminated glass with which the rigidity of laminated glass can be enhanced, the sound insulating properties of laminated glass can be heightened and the recyclability of the interlayer film can be enhanced. The interlayer film for laminated glass according to the present invention includes a first layer and a second layer arranged on a first surface side of the first layer, the first layer contains a polyvinyl acetal resin and a second resin component, the second layer contains a polyvinyl acetal resin, the peak temperature of the loss tangent exhibited by the second resin component in the first layer is -30°C or higher and 10°C or lower, and the refractive index of the second resin component in the first layer is 1.47 or higher and 1.51 or lower.
