The present invention provides an interlayer film for laminated glass that is capable of obtaining a laminated glass that has excellent heat shielding properties and that can suppress the generation of foaming and the growth of foaming. In the case of a single layer structure, an interlayer film for laminated glass 21A according to the present invention includes a first layer 21 containing a thermoplastic resin, a plasticizer, and an infrared absorber. In the case of a laminated structure of two or more layers, the interlayer film 1 for laminated glass according to the present invention includes first and second layers 2 and 3 containing a thermoplastic resin and a plasticizer, The layer 2 or the second layer 3 contains an infrared absorber. The proportion of the high molecular weight component having an absolute molecular weight of 1 million or more in the thermoplastic resin in the first layers 2 and 21 is 7.4% or more, or the thermoplastic resin in the first layers 2 and 21 The proportion of the high molecular weight component having a molecular weight of 1 million or more in terms of polystyrene is 9% or more.
