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
