Interlayer for laminated glass and laminated glass

Abstract

There is provided an interlayer film for laminated glass with which the flexural rigidity of laminated glass can be enhanced and the sound insulating properties of laminated glass can be enhanced. The interlayer film for laminated glass according to the present invention includes a thermoplastic resin, and has a smallest value of the shear storage elastic modulus in a temperature region of 10° C. or more and 40° C. or less measured at a frequency of 0.5 Hz of 3 MPa or more, a ratio of a shear storage elastic modulus at 20° C. measured at a frequency of 0.5 Hz to a shear storage elastic modulus at −30° C. measured at a frequency of 0.5 Hz of 0.01 or more and 0.8 or less, a glass transition temperature falling within the range of −20° C. or more and 0° C. or less, and a largest value of tan δ in a temperature region of −20° C. or more and 0° C. or less of 0.1 or more.
