摘要： The present invention aims to provide an interlayer film for laminated glass which, while having recesses in the shape of engraved lines, enables the production of a laminated glass with high production efficiency by a nip roll method; a roll of the interlayer film for laminated glass; a laminated glass including the interlayer film for laminated glass; and a method of producing laminated glass. The present invention relates to an interlayer film for laminated glass. The interlayer film includes, on at least one surface thereof, a large number of recesses and a large number of projections. The recesses have a groove shape with a continuous bottom. The recesses are adjacently arranged regularly side by side in parallel with one another. The recesses in a groove shape with a continuous bottom are inclined 55° or less relative to the machine direction of the film in production of the interlayer film for laminated glass.
