摘要
The present invention aims to provide an embossed thermoplastic resin sheet that is capable of enhancing deaeration during production of laminated glass and suppressing optical distortion of the resulting laminated glass to improve the visibility when used as an interlayer film for laminated glass. The present invention also relates to an engraved roll used for production of the embossed thermoplastic resin sheet, a production method of the engraved roll, an interlayer film for laminated glass including the embossed thermoplastic resin sheet, and a laminated glass. The present invention relates to an embossed thermoplastic resin sheet 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 arranged side by side in parallel with one another, the thermoplastic resin sheet having not more than three defects of the projections per mm 2 on the surface.
