Abstract
Provided is an interlayer film for laminated glass capable of suppressing multiple images. An interlayer film for laminated glass according to the present invention is used while it is arranged between a first lamination glass member having a wedge angle of 0.10 mrad or more, and a second lamination glass member; the interlayer film has a wedge angle of less than 0.10 mrad, and has a maximum value of partial wedge angles A of 0.15 mrad or less when the partial wedge angles A of the interlayer film are measured in 'the step 1 of selecting points A at 2-mm intervals starting at the position of 20 cm from the one end toward the other end of the interlayer film and ending at the position of 20 cm from the other end toward the one end of the interlayer film' and 'the step 2 of calculating the partial wedge angles A of the interlayer film in each partial region A of 80 mm centered at each of the points A in the direction connecting the one end and the other end' in this order.
