US Patent 7442330 Method and apparatus of manufacturing reflector

A method and an apparatus of manufacturing a reflector which productivity is excellent, the photosensitive resin layer is not changed during the period from a transferring step to an ultraviolet ray irradiating step, and post-process such as a fine hole forming step is easily preformed are provided. The method of manufacturing the reflector comprising the steps of forming a photosensitive resin layer on a sheet base body; transferring a shape of prominence and depression onto the 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 the photosensitive resin layer, wherein the transfer roller has a transfer surface having a prominence and depression pattern at the periphery thereof; and preliminarily irradiating ultraviolet ray onto the photosensitive resin layer immediately after the transferring step is employed.
