Abstract
There is provided an interlayer film for laminated glass which is high in heat shielding properties. The interlayer film for laminated glass according to the present invention includes an infrared ray reflection layer which reflects infrared rays, a first resin layer which is arranged on a first surface side of the infrared ray reflection layer and contains a thermoplastic resin and a second resin layer which is arranged on a second surface side of the infrared ray reflection layer and contains a thermoplastic resin, and the infrared ray transmittance in the wavelength of 780 to 2100 nm of the first resin layer is higher by 10% or more than the infrared ray transmittance in the wavelength of 780 to 2100 nm of the second resin layer.
