Abstract
Provided is an interlayer film for laminated glass capable of reducing the variation in double images in laminated glass in the direction perpendicular to the direction connecting one end and the other end of the interlayer film, and effectively suppressing double images. An interlayer film for laminated glass according to the present invention has one end and the other end being at the opposite side of the the one end, the other end has a thickness of larger than a thickness of the one end, the interlayer film for laminated glass as a whole has a wedge angle of 0.1 mrad or more, and the interlayer film for laminated glass has a thickness varying region in a region extending in the direction perpendicular to the direction connecting the one end and the other end of the interlayer film, having a standard deviation of 11 partial wedge angles measured by the following measuring method of 0.040 mrad or less.
