The present invention provides an interlayer film for laminated glass, which can improve the sound insulation of the obtained laminated glass when the interlayer film for laminated glass is used to form a laminated glass. The interlayer film (2A, 12) for laminated glass of the present invention has a one-layer structure with only the first layer (2) or has a first layer (14) and laminated on at least one surface of the first layer (14). A laminated structure of more than two layers of the second layer (13, 15) of the layer. The first layer (2, 14) contains a thermoplastic resin and a first plasticizer represented by the following formula (1). The present invention is a one-layer structure or a laminated structure of two or more layers and the first layer (2, 14) also contains a second plasticizer as a diester compound or a laminated structure of two or more layers and the second layer (13 , 15) containing a polyvinyl acetal resin and a plasticizer with a hydroxyl content rate of 25 to 40 mol%. |
