摘要： The present invention aims to provide an intermediate film for laminated glass which, in the case of being used for constituting a laminated glass, enables to improve the sound-insulating property in a high frequency range of the obtained laminated glass over a wide range of temperature. The intermediate film for laminated glass of the present invention 1 has a structure that a first layer 2, a second layer 3, and a third layer 4 are laminated in this order, each of the first, second, and third layers 2, 3, and 4 contains a polyvinyl acetal resin and a plasticizer, the hydroxy group content in the polyvinyl acetal resin contained in the first layer 2 is lower than each of the hydroxy group contents in the polyvinyl acetal resins contained in the second and third layers 3 and 4, and the ratio (T1/(T2+T3)) of the thickness (T1) of the first layer 2 to the total thickness (T2+T3) of the second and third layers 3 and 4 is 0.14 or lower.
