Intermediate film for laminated glass, and laminated glass

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.
