Abstract:
Provided is an interlayer film for laminated glass capable of suppressing occurrence of foaming in an end part of the laminated glass, and increasing the transparency of the laminated glass without conducting a high-temperature and high-pressure process by an autoclave. The interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass, having a one-layer structure or a two or more-layer structure, and includes a first layer, and when a specific compression creep test is conducted for a test sample A having a diameter of 8 mm and a thickness of 0.8 mm obtained by cutting out the first layer, a variation in thickness of the test sample A before and after the compression creep test is 50 µm or more and 325 µm or less.
