ABSTRACT:
Provided is an optical member capable of keeping a high performance antireflection effect over a long period of time with respect to an arbitrary substrate. The optical member has plural layers on a substrate, and includes at least one metal oxide layer having a void, and at least one layer containing an organic resin as a main component formed between the substrate and the metal oxide layer. The metal oxide layer is a plate crystal layer formed of a plate crystal containing aluminum oxide as a main component and a surface of the plate crystal layer has an uneven profile. The organic resin has an aromatic ring and/or a hetero ring in at least a part thereof.
