To provide an interlayer for a glass laminate capable of providing the glass laminate, in which wrinkle is hardly generated in the interlayer and a poor appearance is suppressed.SOLUTION: An interlayer for a glass laminate has an MD direction and a TD direction, one end and the other end having a thicker thickness than that of the one end at an opposite side to the one end, the one end and the other end are positioned at both sides of the TD direction of the interlayer, and an absolute value of a difference between a maximum thermal shrinkage and a minimum thermal shrinkage is 5% or less out of three thermal shrinkages; a first thermal shrinkage at a first position of 0.05X from the one end to the other end in the MD direction at 150°C, a second thermal shrinkage at a second position of 0.5X from the one end to the other end in the MD direction at 150°C, and a third thermal shrinkage at a third position of 0.95X from the one end to the other end in the MD direction at 150°C, where X is a distance between the one end and the other end.SELECTED DRAWING: Figure 1

    【課題】中間膜にしわが生じ難く、外観不良が抑えられた合わせガラスを得ることができる合わせガラス用中間膜を提供する。【解決手段】本発明に係る合わせガラス用中間膜は、MD方向とTD方向とを有し、一端と、前記一端とは反対側に前記一端よりも厚い厚みを有する他端とを有し、前記一端及び前記他端は、中間膜のTD方向の両側に位置しており、前記一端と前記他端との間の距離をXとしたときに、前記一端から前記他端に向かって0.05Xの第1の位置のMD方向における150℃での第1の熱収縮率と、前記一端から前記他端に向かって0.5Xの第2の位置のMD方向における150℃での第2の熱収縮率と、前記一端から前記他端に向かって0.95Xの第3の位置のMD方向における150℃での第3の熱収縮率との3つの熱収縮率のうち、最大の熱収縮率と最小の熱収縮率との差の絶対値が5%以下である。【選択図】図1
