There is provided an interlayer film for laminated glass with which an air bubble can be made difficult to be left behind between a lamination glass member and the interlayer film when laminated glass is obtained. The interlayer film for laminated glass according to the present invention contains a thermoplastic resin and has one end and the other end being at the opposite side of the one end and having a thickness thicker than the one end, each of three values of the ten-point average roughness Rz of the surface at a position apart from the one end by 50 mm toward the other end, the ten-point average roughness Rz of the surface at a center position between the one end and the other end, and the ten-point average roughness Rz of the surface at a position apart from the other end by 50 mm toward the one end is 20 µm or more, and a value calculated by subtracting the smallest value among the three values from the largest value among the three values is 3 µm or more and 9 µm or less.
