Abstract: Provided is an optical component including a cyclic olefin-based copolymer (A), in which the cyclic olefin-based copolymer (A) has a constitutional unit (a) derived from at least one olefin represented by the following general formula (I), a constitutional unit (b) derived from at least one cyclic olefin represented by the following general formula (II), and a constitutional unit (c) derived from at least one cyclic olefin represented by the following general formula (III), and the content of the constitutional unit (a) is equal to or less than 50 mol % in a case where the total content of the constitutional unit (a), the constitutional unit (b), and the constitutional unit (c) is taken as 100 mol %.

Abstract: Provided is a method for producing a concave-convex structure, the method including a preparation step of preparing a laminate including a base material layer, a photocurable resin layer containing a fluorine-containing cyclic olefin polymer (A), a photocurable compound (B) and a photocuring initiator (C), and a protective film layer in this order; a peeling step of peeling the protective film layer of the laminate; a pressing step of pressing a mold against the photocurable resin layer exposed in the peeling step; and a light irradiation step of irradiating the photocurable resin layer with light, in which a concave-convex structure having an inverted concave-convex pattern of the mold is produced.
