Provided is an optical film manufacturing method which includes: a coating process wherein a coating layer (12) is formed by coating a coating liquid containing an active energy ray-curable resin on a substrate film (11) which is being continuously conveyed; a first curing process wherein active energy rays are irradiated, from the coating layer (12) side, on a fore-region (A) of the coating layer (12); and a second curing process wherein, with the surface of a mold pushed against the surface of the coating layer (12), active energy rays are irradiated on the coating layer (12), from the substrate film (11) side. In the first curing process, it is preferable to also irradiate active energy rays onto a rear region (B) of the coating layer (12). Thus, the present invention provides a method which enables the continual efficient manufacture of an optical film, whilst being able to prevent the generation of resin remains on the mold, and without generating flaws such as defects. |
