PURPOSE:To make it possible to easily form a duplicate matrix mold having good mold release characteristics by eliminating a gap into which a duplicate material is penetrated, by integrating attachment jig to a mold and the duplicate mold. CONSTITUTION:An attachment jig 2 (30mm.phiX50mm.L) is adhered to a glass plate 1 and resist 3 is applied to the glass plate 1 while a desired shape is imparted to the resist layer. In addition, nickel is further vapor deposited on the resist layer and nickel electrotyping is performed thereon. After electrotyping, the formed composite is released from the glass plate by using a general org. solvent to obtain a nickel duplicate matrix plate 4 (a thickness of 0.3mm.). This duplicate matrix mold 4 is attached to a mold 5 and a plaxtic material (PMMA) is pressed under a press condition of 210 deg.CX30sec to prepare a duplicated product. As a result, a disc shaped duplicated product (an outer diameter of 300mm., a thickness of 1.5mm.) has good mold release characteristics and is strong against damage.
