Abstract:

To manufacture a cylindrical mold having an uneven pattern without a deterioration of a precision.

The first uneven pattern 2 is formed on the cylinder tube 1 as a mother mold as shown in Fig. 1(A). The manufacturing method of the mold comprises the steps of: forming a silicone resin layer 3 on the resist surface of the cylinder 1 on which the first uneven pattern 2 is formed as shown in Fig. 1(B); mounting a cylindrical holder 4 in the circumference of the silicone resin layer 3; peeling the cylinder 1 and the first uneven pattern 2 from the silicone resin layer 3 using the cylindrical holder 4 as shown in Fig. 1(D); fixing the silicone resin layer 3 in the inside of the holder 4; forming a conductive film (conductive layer) 5 on the inner circumferential surface of the silicone resin layer 3 as shown in Fig. 1(E); plating the conductive layer 5 to precipitate a metal layer 6 as shown in Fig. 1(F); and removing the holder 4 and the silicone resin layer 3 to obtain the cylindrical mold 4 as shown in Fig. 1(G).
