PURPOSE:To electroform small-sized parts of a uniform thickness by forming a ring-shaped dummy pattern around patterns corresponding to the small-sized parts to be electroformed and by supplying electric current. CONSTITUTION:A plating resist 2 is applied to a substrate 1 for electroforming so as to form patterns 3 corresponding to the symbols on the dial of a wrist watch and a ring-shaped dummy pattern 4 around the patterns 3. Electroforming 5 is then carried out on the patterns 3, 4 at the same time. Thus, electroformed products are obtd. with extremely reduced ununiformity in thickness, the appearance and quality are improved and the working efficiency is enhanced.
