題点があった。In the second method, a metal stannoplate (6) electrolytically nickel plated on a glass master 6 at about 60 degrees Celsius (6) has a heat shrinkage rate difference with the glass master 5 when the temperature drops to room temperature and residual stress during plating. The glass master 6 is warped by about 100 to 200 μm toward the metal stamper e. In this state, the reinforcing plate 8 is fixed to the back side of the metal stamper 6 via the adhesive 7, so the glass master 6 is bent after reinforcing the back side of the stamper. When the metal stamper 6 was peeled off from the master 6, the signal surface of the metal stamper 6 became convex, and there was a problem that good planarity of the signal surface could not be obtained during replication using an ultraviolet curing resin.

となる。Function According to the present invention, since the reinforcing plate is fixed to the back surface of the metal stamper while applying a pressing force through an adhesive before peeling the metal stamper from the glass master, the metal stamper generated during electrolytic nickel plating is removed. It is possible to eliminate warping due to residual stress and the difference in thermal shrinkage rate between the glass master and the metal stamper, and to fix the reinforcing plate with an adhesive while the metal stamper and the glass master are flat. Therefore, the signal surface of the metal stamper peeled off from the glass master after reinforcing the back surface of the metal stamper has excellent flatness.
