Abstract
Provided is an interlayer film for laminated glass that can improve bending rigidity and sound insulating properties of laminated glass and can inhibit the occurrence and growth of foam in the laminated glass. An interlayer film for laminated glass according to the present invention has a single-layer structure or a two or more-layer structure and includes a first layer containing a polyvinyl acetal resin and a plasticizer, in which a glass transition temperature of the first layer is 10° C. or lower, and an elastic modulus of the first layer at 30° C. is 285,000 Pa or greater.
