In the manufacture of a first electroformed component (40) and a second electroformed component (60) having parts which are brought into close contact with each other when the components are engaged, after the first electroformed component (40) is formed, the second electroformed component (60) is formed using the first electroformed component (40) as part of an electroforming mold. The use of the first electroformed component (40) as part of an electroforming mold to form the second electroformed component (60) enables the shape of the first electroformed component (40) to be transferred to the second electroformed component (60). This enables different types of components with different shapes to be precisely manufactured at one time in a series of manufacturing processes.
