Abstract
Provided is an interlayer film for laminated glass capable of keeping the haze value low when a heat resistance test at 100° C. is conducted for the laminated glass, although the interlayer film has a polyethylene terephthalate film. An interlayer film for laminated glass according to the present invention includes a first resin layer containing a thermoplastic resin, a polyethylene terephthalate film, and a second resin layer containing a thermoplastic resin, in this order, and has a ratio of absorbance A at a wavelength of 1930 nm to absorbance B at a wavelength of 1705 nm of 0.50 or less.
