An optical film which enables desired optical properties to be obtained easily, and enables the durability to be improved. A metal film 32 is formed on an inner major surface 12 a of a glass substrate 12 . A plurality of first island structures 33 is formed scattered as islands on an inner major surface 32 a of the metal film 32 . A plurality of second island structures 31 is formed scattered as islands on the inner major surface 12 a of the substrate 12 . At least one set of the plurality of first island structures 33 and the plurality of second island structures 31 are made of at least one selected from the group consisting of metals and metal oxides having a different standard electrode potential to a metal of the metal film 32. |
