PROBLEM TO BE SOLVED: To stably mass-produce a good quality molding by opening a mold without applying a load to the peripheral end of a molding in a molding ejection process and ejecting the molding without deforming a burr formed at the peripheral end of the molding. SOLUTION: In the molding ejection process, mold opening is started after a vent clearance 12 is enlarged by moving-back a peripheral ring 7 forming the vent clearance 12 with a stamper 4, the mold is opened without applying bending force to the burr 15 formed by a resin introduced into the vent clearance 12, and the molding is ejected without deforming the burr 15 formed along the surface of the molding to which a relief pattern formed on the surface of the stamper 4 is transferred.
