Abstract:

Provided is an intermediate film for a laminated glass, the intermediate film being capable of increasing the adhesion of a plastic layer and a resin layer and being capable of increasing the handleability of the laminated glass. According to the present invention, an intermediate film for a laminated glass is provided with a plastic layer that has a Young's modulus of 1 GPa or more and a first resin layer that is laminated on a first surface of the plastic layer, and is provided with a second resin layer that is laminated on a second surface that is opposite the first surface of the plastic layer or is not provided with the second resin layer on the second surface that is opposite the first surface of the plastic layer. With regard to a width-direction cross section of the intermediate film, when a first laminate interface of the plastic layer and of the first resin layer is observed, of 100% of the length of the surface of the plastic layer at the first laminate interface, the proportion occupied by the length of a portion that does not contact the first resin layer that is on the surface of the plastic layer at the first laminate interface is 75% or less.
