PROBLEM TO BE SOLVED: To provide an interlayer for a laminated glass excellent in antiblocking properties of the interlayer for the laminated glass to each other during preservation, and treatability when sandwiching the interlayer between glass plates, and further excellent in deaerating properties at a previous contact- bonding step. SOLUTION: This interlayer for the laminated glass has original emboss comprising fine ruggedness formed on a thermoplastic film, and the shape of the concave part is a groove shape. The ratio (SmA/SmB) of the average interval (SmA) of the original emboss to the interval (SmB) of the grooves of the concave parts is regulated so as to be 0.5-1.5.
