To provide an interlayer for a glass laminate capable of inhibiting a transmitting double image in a glass laminate.SOLUTION: An interlayer for a glass laminate includes one end and the other end on an opposite side of the one end. The other end is thicker than the one end. According to a calculation of a formula of a specific approximation straight line A and a deviation of a partial wedge angle, when a tilt of the approximation straight line A and a maximum value of an absolute value of the deviation of the partial wedge angle are calculated, at least in one interval A, the tilt of the approximation straight line A is -0.05 mrad/m or less, and the maximum value of the absolute value of the deviation of the partial wedge angle is 0.2 mrad or less.SELECTED DRAWING: Figure 1

    【課題】合わせガラスにおける透過二重像を抑え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、一端と、前記一端の反対側に他端とを有し、前記他端の厚みが、前記一端の厚みよりも大きく、特定の近似直線Aの式及び部分楔角の偏差の算出に基づいて、前記近似直線Aの傾き及び前記部分楔角の偏差の絶対値の最大値を算出したときに、少なくとも1つの区間Aにおいて、前記近似直線Aの傾きが-0.05mrad/m以下であり、かつ前記部分楔角の偏差の絶対値の最大値が0.2mrad以下である。【選択図】図1
