Abstract
An optical member includes a laminated body configured to reduce light reflection disposed on a substrate, wherein a surface of the laminated body is a porous layer or a layer having a textured structure, and at least one layer of the laminated body is a polymer layer containing a linear polymer and a branched polymer. A method for manufacturing the optical member is also provided. The branched polymer content is 10% by weight or more and 90% by weight or less of the total weight of the linear polymer and the branched polymer. The layer having a textured structure contains crystals mainly composed of aluminum oxide.
