INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS

The present invention aims to provide an interlayer film for a laminated glass that adheres sufficiently to glass at peripheral portions of the glass to prevent occurrence of a sealing failure at the peripheral portions and also to contribute to improved production efficiency of laminated glass in production of laminated glass, even when having a thickness at the thickest portion of 850 pm or more, and a laminated glass produced using the interlayer film for a laminated glass. Provided is an interlayer film for a laminated glass having a large number of recesses on at least one surface, the interlayer film for a laminated glass having a thickness T (µm) measured in conformity with JIS K-6732 (1996) and a maximum height roughness Ry (µm) measured in conformity with JIS B-0601 (1994) at a thickest portion, the thickness T and the maximum height roughness Ry satisfying the following expressions (1) and (1'): Ry≤0.0195×T+33.2T≥850
