An optical film including, in this order: a first layer containing a hydrogenated product of an aromatic vinyl compound-conjugated diene compound block copolymer; a second layer containing a norbornene-based polymer; and a third layer containing a hydrogenated product of an aromatic vinyl compound-conjugated diene compound block copolymer. Preferably, the hydrogenated product of the aromatic vinyl compound-conjugated diene compound block copolymer is a hydrogenated product of a styrene-isoprene copolymer. Preferably, a copolymerization ratio of styrene/isoprene in the hydrogenated product of the styrene-isoprene copolymer is 50/50 to 90/10.
