The present invention aims to provide an interlayer film for a laminated glass which enables production of a laminated glass with suppressed occurrence of optical distortion, a method for producing the interlayer film for a laminated glass, and a laminated glass produced using the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass produced by an extrusion lip embossing method utilizing melt fracture, the interlayer film for a laminated glass including a laminate that includes two or more resin layers in a stack and having a large number of protrusions and recesses on at least one surface, a maximum height Ry (μm) and an average interval Sm (μm) of the protrusions and recesses measured in conformity with JIS B 0601 (1994) on the surface with protrusions and recesses satisfying a formula (1): (Ry×Sm)/2≤3,500  (1).
