Abstract:
There is provided an interlayer film for laminated glass with which double images in laminated glass can be considerably suppressed. The interlayer film for laminated glass according to the present invention has one end and the other end being at the opposite side of the one end, makes the thickness of the other end larger than the thickness of the one end, has a display corresponding region corresponding to a display area of the head-up display, and when a position apart from an end part at the one end side of the display corresponding region by 4 cm toward the other end is set to a start point, a position apart from an end part at the other end side of the display corresponding region by 4 cm toward the one end is set to an end point, spots are selected at 2-mm intervals from the start point to the end point, and the interlayer film is measured for the amount of change in the thickness within respective segments, centered on the respective spots, of 80 mm in a direction connecting the one end and the other end, makes the absolute value of a difference between the largest value among values of the amount of change in the thickness and the smallest value among values of the amount of change in the thickness 32 μm or less.
