Abstract
A first object of the invention is to provide an interlayer film for laminated glass which has excellent sound insulating properties and heat shielding properties, and a laminated glass using the same. Further, a second object of the invention is to provide an interlayer film for laminated glass capable of maintaining the sound insulating properties, weather resistance, and heat creep resistance at a high level even if the thickness is reduced, and a laminated glass using the same. The invention relates to an interlayer film for laminated glass, including at least one layer A containing a thermoplastic elastomer, wherein a laminated glass in which the interlayer film for laminated glass is disposed between two clear glasses with the total thickness of the clear glasses being 4 mm or less has a visible light transmittance of 70% or more and an average transmittance of infrared light in the wavelength range of 800 to 1,100 nm of 72% or less.
