An objective of the present invention is to provide an organic glass laminate that exhibits excellent weathering resistance and abrasion resistance, and that can be used as an exterior member. This organic glass laminate comprises at least the following, in order: an organic glass base, a cured layer formed from the cured product of a resin composition, which comprises a curable resin and a UV absorber agent; and an inorganic oxide film. The glass transition temperature of the cured product which constitutes the cured layer is adjusted to 80-160&#xb0; C., and the thickness of the inorganic oxide film is set to at least 0.01 &#x3bc;m and less than 0.5 &#x3bc;m, whereby weathering resistance and abrasion resistance are significantly improved, and the organic glass laminate is made suitable for use as an exterior member.
