Abstract: Provided is an interlayer film for laminated glass capable of enhancing the adhesive force between a layer containing a (meth)acryloyl polymer, and an adherend arranged on the layer, and enhancing the sound insulating property of the laminated glass. An interlayer film for laminated glass according to the present invention has a one-layer or two or more-layer structure, the interlayer film includes a first layer containing a (meth)acryloyl polymer prepared by polymerizing polymerization components including at least one kind of cyclic skeleton-containing (meth)acryloyl monomer selected from the group consisting of a (meth)acryloyl monomer having an aromatic skeleton, a (meth)acryloyl monomer having an alicyclic skeleton and a (meth)acryloyl monomer having a cyclic ether skeleton, and a content of the cyclic skeleton-containing (meth)acryloyl monomer is 50% by weight or more in 100% by weight of the polymerization components.
