To provide an interlayer for a glass laminate capable of considerably suppressing a double image in the glass laminate.SOLUTION: An interlayer for a glass laminate according to the present invention includes: one end; the other end having a thickness larger than that of the one end; and a display corresponding area corresponding to a display area of a head-up display, in which when a first partial wedge angle θ1 in each partial area of 80 mm in a direction connecting the one end and the other end of the display corresponding area is calculated, and a second partial wedge angle θ2 in each second partial area of 40 mm in the direction connecting the one end of the display corresponding area and the other end is calculated, and |θ1-θ2| is calculated from θ1 in the first partial area and θ2 of the second partial area which have the same center point in the direction connecting the one end and the other end, the maximum value of all |θ1-θ2| is 0.2 mrad or smaller, the wedge angle of the entire interlayer is 0.1 mrad or larger.SELECTED DRAWING: Figure 1

    【課題】合わせガラスにおける二重像をかなり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、前記一端よりも厚みが大きい他端とを有し、ヘッドアップディスプレイの表示領域に対応する表示対応領域を有し、前記表示対応領域の前記一端と前記他端とを結ぶ方向の80mmの各第1の部分領域における第1の部分楔角θ1を算出し、かつ、前記表示対応領域の前記一端と前記他端とを結ぶ方向の40mmの各第2の部分領域における第2の部分楔角θ2を算出して、前記一端と前記他端とを結ぶ方向の中心地点が同じ前記第1の部分領域でのθ1と前記第2の部分領域でのθ2とから|θ1−θ2|を算出したときに、全ての|θ1−θ2|のうちの最大値が0.2mrad以下であり、前記中間膜全体での楔角が0.1mrad以上である。【選択図】図1
