    摘要： The present invention aims to provide an interlayer film for laminated glass which can suppress the transmittance of ultraviolet rays with a wave length of 400 nm to 1% or less, and has high light resistance; and laminated glass including the interlayer film for laminated glass. The present invention provides an interlayer film for laminated glass including a thermoplastic resin, an ultraviolet absorber having a structure represented by the following formula (1), and an ultraviolet absorber having a structure represented by the following formula (2), wherein the amount of the ultraviolet absorber having a structure represented by the following formula (1) is 0.001 to 0.05% by weight, and the amount of the ultraviolet absorber having a structure represented by the following formula (2) is 0.4 to 1.5% by weight.

    In the formula (1), R 1 represents a C1 to C3 alkyl group, and R 2 represents hydrogen, a C1 to C10 alkyl group, or a C7 to C10 aralkyl group.
    In the formula (2), R 3 represents hydrogen or a C1 to C8 alkyl group, and R 4 represents hydrogen or a C1 to C8 alkyl group.
