Abstract
There is provided an interlayer film for laminated glass with which a low yellow index value, low excitation purity and high heat shielding properties can be achieved in spite of the thickness varying with places. The interlayer film for laminated glass according to the present invention has a thickness of one end thinner than a thickness of the other end at the opposite side of the one end and includes a thermoplastic resin, an ultraviolet ray screening agent and tungsten oxide particles, and the ultraviolet ray screening agent is a benzotriazole-based ultraviolet ray screening agent.
