A first object of the invention is to provide an interlayer film for laminated glass, which can brighten the entire room by suppressing reduction of the amount of solar light penetrating through a laminated glass and efficiently diffusing the penetrated light, and a laminated glass using the interlayer film. A second object of the invention is to provide a production method for recycling a trim or an out-of-specification product of an interlayer film for laminated glass, the interlayer film using a polyvinyl acetal resin layer and a thermoplastic elastomer layer, and thereby obtaining an interlayer film for laminated glass having secured light transmission properties and light scattering properties. The invention relates to an interlayer film for laminated glass having layer A containing a polyvinyl acetal resin, in which a thermoplastic elastomer is dispersed in layer A, and in the case of producing a laminated glass using the interlayer film, the laminated glass has a haze of 10% or higher and a total light transmittance of 80% or higher.
