摘要：The present invention aims to provide an interlayer film for a laminated glasswhich has a multilayer structure including two or more resin layers laminated togetherand can prevent optical distortion even at high temperatures, a laminated glass includingthe interlayer film for a laminated glass, and a method of producing the interlayer filmfor a laminated glass. The present invention relates to an interlayer film for a laminatedglass, the interlayer film including: two or more resin layers laminated together, one resinlayer having a surface with a ratio (Rz/Sm) of a ten-point average roughness Rz (µm) to anaverage interval Sm (µm) of projections and recesses of 0.0018 or less as measured inconformity with JIS B-0601(1994) in the following manner: a laminated glass is producedusing two clear glass sheets conforming to JIS R3202(1996) and the interlayer film; theinterlayer film is peeled away from the clear glass sheets after the laminated glass iscooled with liquid nitrogen; the one resin layer is peeled away from another resin layerthat is in direct contact with the one resin layer; and the Rz and Sm of the surface of the

one resin layer on the side having been in contact with the other resin layer aremeasured.
