1. An interlayer film for laminated glass, comprising 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 an ultraviolet ray shielding agent, a content of the ultraviolet ray shielding agent in 100% by weight of the first resin layer being 0.1% by weight or more, and a second resin layer which is arranged on a second surface side opposite to the first surface of the infrared ray reflection layer and contains a thermoplastic resin, an ultraviolet ray shielding agent and a heat shielding compound, the second resin layer containing both of metal-doped tungsten oxide particles and at least one compound among a phthalocyanine compound, a naphthalocyanine compound and an anthracyanine compound as the heat shielding compound, a content of the at least one compound in 100% by weight of the second resin layer being 0.1% by weight or less,the first resin layer containing or not containing a heat shielding compound, a content in % by weight of the heat shielding compound in the first resin layer being smaller than a content in % by weight of the heat shielding compound in the second resin layer by 0.05% by weight or more, andthe infrared ray transmittance in the wavelength of 780 to 2100 nm of the first resin layer being higher than the infrared ray transmittance in the wavelength of 780 to 2100 nm of the second resin layer.
