The present invention aims to provide an optical layered body that has excellent interlayer adhesiveness, particularly even in outdoor use, and also has highly excellent anti-blocking properties. The present invention relates to an optical layered body including: a substrate film; a hard coat layer containing silica fine particles on at least one surface of the substrate film; and a dry film layer on a surface of the hard coat layer opposite to the substrate film side surface of the hard coat layer, wherein the silica fine particles are exposed on the dry film layer side surface of the hard coat layer; the dry film layer is directly formed on the surface of the hard coat layer on which the silica fine particles are exposed; the hard coat layer before the formation of the dry film layer has projections and depressions on the surface on which the dry film layer is to be formed; the hard coat layer has an average silica fine particle abundance in ten 0.2 μm×0.2 μm regions of 30 to 80% and a standard deviation of silica fine particle abundances in the 10 regions of 1 to 7, where the 10 regions are randomly selected from a cross section of the hard coat layer in the thickness direction within the range from the dry film layer side interface to 10% of the thickness in the thickness direction; and the hard coat layer has a silicon atom abundance A of 2 to 10% on the surface opposite to the substrate film side surface as determined by X-ray photoelectron spectroscopy.
