Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical member having high in-plane uniformity and high reflection prevention performance, and to provide a method of manufacturing the optical member.SOLUTION: In an optical member, a laminated body configured to reduce light reflection is formed on a substrate, a surface of the laminated body is a porous layer or a layer having a textured structure, and at least one layer of other layers is a polymer layer containing a linear polymer and a branched polymer having 1.7 or more of a refractive index. A method for manufacturing the optical member is also provided. A content of the branched polymer is 10 wt.% or more and 90 wt.% or less with respect to a total weight of the linear polymer and the branched polymer. The layer having the textured structure contains crystals mainly composed of aluminum oxide.
