Abstract:
There is provided an interlayer film for laminated glass with which the processability at the time of preparation of laminated glass can be enhanced, furthermore, a large broken piece of glass is hardly generated even when laminated glass is broken, and laminated glass can have a high level of safety. The interlayer film for laminated glass according to the present invention includes a plastic layer with a Young's modulus of higher than or equal to 1 GPa and a first resin layer layered on a first surface of the plastic layer, is provided or not provided with a second resin layer layered on a second surface opposite to the first surface of the plastic layer, has the Young's modulus of the plastic layer higher than the Young's modulus of each of the first and second resin layers, and has an adhesive force between the plastic layer and each of the first and second resin layers measured in accordance with JIS K6854-2 of greater than or equal to 1 N/50 mm and less than or equal to 20 N/50 mm.
