Disclosed herein is a manufacturing method for a molded article having a very fine uneven surface structure wherein, while a laser irradiation region is successively moved with respect to a working face of a working object article for each one shot, a laser beam is repetitively irradiated upon the working face of the working object article, the manufacturing method including the steps of: setting an energy density for the laser beam; setting a number of shots with which a desired fine shape is to be formed; calculating a speed of movement of the laser irradiation region with respect to the working face; and irradiating the laser beam of the set energy density while the working face is moved relative to the laser irradiation region at the calculated speed of movement to form a very fine uneven structure formed from working marks on the working face on which the fine shape is formed.
