Beschreibung
Zusammenfassung:	The present invention provides an interlayer film for a laminated glass which has excellent sound insulation and can suppress bubble formation and bubble growth in the laminated glass, and a multilayer interlayer film for the laminated glass including the interlayer film for a laminated glass. An interlayer film for a laminated glass 2 includes a thermoplastic resin and a plasticizer. The ratio of a high molecular weight component with an absolute molecular weight of 1000000 or more in the thermoplastic resin is 7.4% or higher, or the ratio of a high molecular weight component with a polystyrene-equivalent molecular weight of 1000000 or more in the thermoplastic resin is 9% or higher. A first multilayer interlayer film 1 for a laminated glass includes an interlayer film 2 for a laminated glass and an interlayer film 3 for a laminated glass that contains a thermoplastic resin and a plasticizer, and is laminated on one face 2a of the interlayer film 2 for a laminated glass.
