Abstract: The present invention provides an optical laminate, and a manufacturing method therefor, the optical laminate comprising a substrate and a thermochromic which is formed on the substrate and which comprises vanadium oxide particles, wherein the adhesive strength between the thermochromic layer and the substrate is 50 N/m or greater, and the thermochromic layer is controlled so as to have a specific pore area ratio. The laminate manufactured by the method of the present invention has excellent visible light transmittance and infrared light transmittance.
