Abstract
The present invention aims to provide an interlayer film for a laminated glass capable of exhibiting high deaeration properties even in a nip roll method and hardly forming air bubbles to enable the production of a highly visible laminated glass, and a laminated glass including 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 and a large number of projections on at least one surface, the recesses each having a groove shape with a continuous bottom and being regularly adjacent to each other in parallel with one another, the recesses each having a groove shape with a continuous bottom having a ratio (R/Sm×100) of a radius of rotation R of the bottom to an interval Sm between the recesses of 15% or higher.
