Beschreibung
Zusammenfassung:	The present invention aims to provide an interlayer film for a laminated glass having recesses in the shape of engraved lines on both surfaces to exhibit excellent deaeration properties in production of a laminated glass and suppressing formation of a moire pattern when unwound from a rolled body thereof. The present invention also aims to provide a laminated glass including the interlayer film for a laminated glass, a method for producing an embossing roll suitably used for production of the interlayer film for a laminated glass, and a method for producing the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a large number of recesses on both surfaces, the recesses each having a groove shape with a continuous bottom and being regularly adjacent and parallel to each other, the interlayer film having a glossiness on a surface with the large number of recesses measured in conformity with JIS Z 8741-1997 of higher than 3% or a haze value measured in conformity with JIS K 7105-1981 of 87% or lower.
