An interlayer film for laminated glass is provided with which it is possible to heighten the flexural rigidity of laminated glass. The interlayer film for laminated glass according to the present invention has a single-layer structure or a structure made up of two or more layers, and includes a first layer comprising a polyvinyl acetal resin and a plasticizer. The polyvinyl acetal resin contained in the first layer has a half-value width, regarding hydroxy groups, of 250 cm-1 or less, and the content of the plasticizer in the first layer is 5 parts by weight or larger but less than 30 parts by weight per 100 parts by weight of the polyvinyl acetal resin contained in the first layer. Alternatively, the polyvinyl acetal resin contained in the first layer has a half-value width, regarding hydroxy groups, of larger than 250 cm-1. |
