The present invention provides a transfer method for ultraviolet (UV) optical film and a manufacturing method of a transferring roller by using a deep UV light. The transfer method includes: coating a photoresist (PR) layer onto an outer surface of a metallic roller; emitting a deep UV light having a predetermined exposure wavelength, which forms a predetermined light shape by passing through a mask or an interference, to travel onto the PR layer, so that the PR layer becomes a patterned transfer layer; continuously using the patterned transfer layer to roll onto a UV optical film; and emitting a solidifying UV light having a wavelength in a predetermined light curing band to irradiate and to solidify on the UV optical film being shaped. The predetermined exposure wavelength is less than the predetermined light curing band by at least 100 nm.
