Intermediate film for laminated glass, and laminated glass

Abstract

There is provided an interlayer film for laminated glass with which the flexural rigidity, sound insulating properties and long-term adhesive stability of laminated glass can be enhanced. The interlayer film for laminated glass according to the present invention has a shear storage equivalent elastic modulus of 10 MPa or more and 500 MPa or less in a temperature region of 80% or more of the temperature region of 0° C. or more and 30° C. or less, a value obtained by dividing a shear storage equivalent elastic modulus at 10° C. by a shear storage equivalent elastic modulus at 30° C. of 1 or more and 10 or less, a glass transition temperature falling within the range of −25° C. or more and 0° C. or less, and a largest value of tan δ in a temperature region of −50° C. or more and 0° C. or less of 0.1 or more and 1 or less.
