Abstract
Provided is an interlayer film for laminated glass capable of effectively enhancing the sound insulating property of laminated glass having the interlayer film, in the interlayer film including a layer prepared with a thermoplastic component other than a polyvinyl acetal resin. An interlayer film for laminated glass according to the present invention has a one-layer structure or a two or more-layer structure, and includes a thermoplastic elastomer layer containing a thermoplastic elastomer and a plasticizer, and the thermoplastic elastomer is an aliphatic polyolefin, the thermoplastic elastomer layer has a glass transition temperature in a temperature range of −10° C. to 10° C., and a maximum value of tan δ in a temperature range of −10° C. to 10° C. of the thermoplastic elastomer layer is 1.5 or more.
