Beschreibung
Zusammenfassung:	Provided is an interlayer film for laminated glass capable of enhancing the sound insulating property of laminated glass in a relatively low temperature region. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer structure or a two or more-layer structure, and when the interlayer film is sandwiched between two sheets of green glass having a thickness of 2 mm to obtain a laminated glass X with a size of 25 mm long × 300 mm wide, an absolute value of difference between a secondary resonance frequency of the laminated glass X before irradiation with xenon light and a secondary resonance frequency of the laminated glass X after irradiation with xenon light determined by a specific xenon light irradiation test is 60 Hz or more, a loss factor at 20°C of the laminated glass X is 0.25 or more, and a solar transmittance of the laminated glass X is 50% or less.
