PROBLEM TO BE SOLVED: To provide a manufacturing method for a functional film that is reduced in thickness, superior in terms of surface flatness and smoothness, and free from wavy wrinkles, and to provide such a functional film.SOLUTION: A functional film manufacturing method includes forming a coating layer by coating a functional layer-forming composition containing an ultraviolet-curable compound on a base material film, and forming a functional layer by curing the ultraviolet-curable compound by means of ultraviolet irradiation, where the base material film has a thickness of 5-50 μm. The total irradiance of the ultraviolet irradiation is no less than 100 mJ/cm, and the ultraviolet irradiation is performed such that the maximum illuminance during the time till cumulative irradiance reaches the first 5 mJ/cmis in a range of 5-50 mW/cm.SELECTED DRAWING: None |
