めっき膜の側面図である。(c) Purpose of the Invention The purpose of the present invention is to provide a replica matrix which eliminates the above-mentioned problems by eliminating the machining of the plating film. Structure An object of the present invention is to provide such a reproduction master mold, in which the outer peripheral part of the master is provided with a rib part that fits into the inner peripheral surface of the mold, and the central part is provided with an uneven part that forms a hole for insertion. (c) Examples of the Invention The following describes the present invention. This will be explained in detail with reference to FIG. 2. FIG. 2 is an explanatory diagram of a manufacturing process illustrating an embodiment of a method for manufacturing a mold according to the present invention. (a) is the original 111

2 is provided. Therefore, after forming the plating film 3, °
When the plating film 13 is peeled off from the master, ribs 13-1 and holes 13-2 are formed in the plating film 13, as shown in (c). Therefore, there is no need for conventional press machining, and the plating film 13 can be peeled off and immediately attached to the mold 4. 1 and hole 11-
The plating film 13 is formed by using the substrate 11 provided with the uneven portions 7il-2, etc., and machining unlike the conventional plating film 3 is not required by kneading. Therefore, deformation due to strain and deterioration of mechanical strength can be prevented, the quality of double A discs can be improved and the life of the replica mother mold can be extended, and the practical effects are excellent.
