Patent ID: 7442330

Claim:
A method of manufacturing a reflector, comprising the steps of: forming a photosensitive resin layer on a sheet base body; transferring a prominence and depression pattern onto said photosensitive resin layer, while forwarding the sheet base body in one direction, by rotating a transfer roller having substantially cylindrical shape while pressing the transfer roller against said photosensitive resin layer, the transfer roller having a transfer surface having a prominence and depression pattern at a periphery thereof; preliminarily irradiating ultraviolet ray with respect to said photosensitive resin layer immediately after said transferring step, wherein said preliminary irradiation step does not completely cure said photosensitive resin layer; and main-irradiating the ultraviolet ray with respect to said photosensitive resin layer after said preliminary irradiating step, wherein the main irradiation step performs irradiation via a photomask to form holes in said photosensitive resin layer.
