    摘要: There is provided an interlayer film for laminated glass with which positional displacement between two lamination glass members can be prevented. The interlayer film for laminated glass according to the present invention is arranged between a first lamination glass member and a second lamination glass member to obtain laminated glass, the interlayer film contains a thermoplastic resin and a plasticizer, when, in the MD direction of the interlayer film, a birefringence index of the first surface part, a birefringence index of the second surface part, and a birefringence index of the center part are defined as ΔnMDA, ΔnMDB, and ΔnMDC, respectively, ΔnMDA, ΔnMDB, and ΔnMDC each are 0.50 × 10 -3 or less, and the glass transition temperature of the interlayer film is 33°C or less or the content of the plasticizer in the interlayer film is 35 parts by weight or more relative to 100 parts by weight of the thermoplastic resin in the interlayer film.
