Provided is an intermediate film for laminated glass, which has high heat shielding properties. An intermediate film for laminated glass according to the present invention comprises: an infrared reflecting layer that reflects infrared light; a first resin layer that is arranged on a first surface of the infrared reflecting layer and contains a thermoplastic resin; and a second resin layer that is arranged on a second surface of the infrared reflecting layer and contains a thermoplastic resin. The infrared light transmittance of the first resin layer at a wavelength of 780-2,100 nm is higher than the infrared light transmittance of the second resin layer at a wavelength of 780-2,100 nm by 10% or more. 本发明提供种隔热性高的夹层玻璃用中间膜。本发明的夹层玻璃用中间膜具备：反射红外线的红外线反射层、配置于红外线反射层的第表面侧且含有热塑性树脂的第树脂层、配置于红外线反射层的第二表面侧且含有热塑性树脂的第二树脂层，第树脂层在波长780～2100nm下的红外线透射率比第二树脂层在波长780～2100nm下的红外线透射率高10％以上。
