The invention aims to provide an interlayer film for laminated glass which has a multilayer structure composed of two or more resin layers and can prevent optical distortion even at high temperatures, laminated glass comprising the interlayer film for laminated glass, and a method for producing the interlayer film for laminated glass. The interlayer film for laminated glass is a multilayer laminate of two or more resin layers. When laminated glass is produced using two sheets of clear glass according to JIS R3202 (1996), the laminated glass is cooled with liquid nitrogen, the clear glass is peeled from the interlayer film for laminated glass, and then one resin layer is peeled from another resin layer in direct contact therewith. The ratio Rz/Sm of the ten-point average roughness Rz (μm) to the average spacing Sm (μm) of unevenness, measured according to JIS B-0601 (1994), on the surface of the peeled resin layer on the side in contact with the other resin layer is 0.0018 or less.
