PROBLEM TO BE SOLVED: To provide a long-wavelength ultraviolet ray absorbing laminated body which has drastically improved light-fastness and is suitable for various applications such as an ultraviolet ray preventing film for especially, glass as building material or a windowpane for a vehicle. SOLUTION: The long-wavelength ultraviolet ray absorbing laminated body includes: a support; a long-wavelength ultraviolet ray absorbing layer formed of a resin composition containing at least one of ultraviolet ray absorbing agent A, characterized in that the maximum absorption wavelength is 350-400 nm, the half-value width is≤55 nm, and the molar absorbance coefficient is≥20,000 at the maximum absorption wavelength, and a resin; and a short-wavelength ultraviolet ray absorbing layer formed of a resin composition containing at least one of ultraviolet ray absorbing agent B, characterized in that the maximum absorption wavelength is≤350 nm and the absorbance at 320 nm is≥30% of the absorbance at the maximum absorption wavelength, and a resin, on the incident light side of the long-wavelength ultraviolet ray absorbing layer.
