Abstract
The present invention provides an intermediate film for laminated glass that can increase the heat-insulating properties of laminated glass. The intermediate film for laminated glass according to the present invention is an intermediate film for laminated glass having a one-layer structure or a laminated structure of two or more layers, an intermediate filmfor laminated glass has a first layercontaining silicon dioxide particleshaving hollow parts and shell parts and having a porosity of 40% or more and 80% or less, when the intermediate filmfor laminated glass has a one-layer structure, the first layer further contains a thermoplastic resin, and when the intermediate filmfor laminated glass has a laminated structure of two or more layers, the intermediate filmfor laminated glass further has a second layerwhich is arranged on a first surfaceside of the first layerand which contains a thermoplastic resin.
