PROBLEM TO BE SOLVED: To provide a laminate which causes no change in sound insulation properties due to moisture content and has a small temperature dependency of sound insulation properties when used for an intermediate film of a laminated glass. ! SOLUTION: There is provided a laminate which comprises: an A layer of a compound (I) specifically including triethyleneglycol di 2-ethylhexanoate and tetraethyleneglycol di 2-ethylhexanoate having a content of Wa1 pts.wt. and a compound (II) specifically including triethyleneglycol mono 2-ethylhexanoate and tetraethyleneglycol mono 2-ethylhexanoate having a content of Wa2 pts.wt. based on 100 pts.wt. of a polyvinyl acetal (A) having an average residual hydroxyl group amount of 25 to 45 mol%; and a B layer of the compound (I) having a content of Wb1 pts.wt. and the compound (II) having a content of Wb2 pts.wt. based on 100 pts.wt. of a polyvinyl acetal (B) having an average residual hydroxyl group amount of 10 to 35 mol%, where Wa1, Wa2, Wb1 and Wb2 satisfy a |
