A Fresnel lens base sheet is provided which is suitable for the formation of a lens layer of an ultraviolet-cured resin and has excellent impact resistance and environmental resistance. The Fresnel lens base sheet comprises a specific rubber-modified styrene resin comprising a rubber-like elastic material as dispersed particles and a copolymer of a styrene monomer with an acrylic (methacrylic) ester monomer as a continuous phase.
