FIELD: glass. SUBSTANCE: invention relates to laminated glass obtained using an interlayer film for laminated glass. Interlayer film for laminated glass contains a thermoplastic resin and has one end and the other end on the opposite side from it， the thickness of which is greater than the thickness of the first end. Each of three values - average roughness Rz by ten points of microrelief of surface in position， spaced from one end by 50 mm towards other end， average roughness Rz by ten points of microrelief of surface in central position between one end and other end and average roughness Rz by ten points of microrelief of surface in position spaced from other end by 50 mm towards one end - is 20 mcm or more， and the value obtained by subtraction of the smallest of these three values from the largest of the three values is 3 mcm or more and 9 mcm or less. EFFECT: technical result is reduced probability of presence of residual air bubble between laminated glass element and interlayer film during production of laminated glass. 7 cl， 12 dwg， 1 tbl
