摘要： The present invention provides an interlayer film for a laminated glass capable of suppressing bubble formation and bubble growth even if the laminated glass is exposed to relatively high temperatures for a long time. An interlayer film for a laminated glass according to the present invention includes a first layer and a second layer laminated on one face of the first layer, each of the first layer and the second layer contains a polyvinyl acetal resin and a plasticizer, and in the case of measuring the viscoelasticity of the first layer as a resin film (glass transition temperature: Tg(° C.)), or the viscoelasticity of a resin film (glass transition temperature: Tg(° C.)) containing 100 parts by weight the polyvinyl acetal resin in the first layer and 60 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO) as a plasticizer, the resin film has an elastic modulus of G′(Tg+170) at (Tg+170)° C. and an elastic modulus of G′(Tg+30) at (Tg+30)° C., and provides a ratio (G′(Tg+170)/G′(Tg+30)) of 0.18 or higher.
