There is provided an interlayer film for laminated glass with which double images and uneven appearance by light can be effectively suppressed. An interlayer film for laminated glass (11) according to the present invention includes a first layer (1) containing a thermoplastic resin and a plasticizer, and a second layer (2) containing a thermoplastic resin and a plasticizer. The first layer (1) has a minimum thickness of 20 µm or more; a ratio B of thickness of the first layer (1) at the other end (11b) to thickness of the interlayer film at the other end (11b) is 1.1 times or more and 1.7 times or less a ratio A of thickness of the first layer (1) at the one end (11a) to thickness of the interlayer film at the one end (11a) when a wedge angle is 0.1 mrad or more and 0.5 mrad or less, and the ratio B is 0.8 times or more and 1.1 times or less the ratio A when the wedge angle is more than 0.5 mrad; and a content of the plasticizer in the first layer (1) is larger than a content of the plasticizer in the second layer (2).
