A contact element (25) (electroformed product) is manufactured by electroforming. An insulating film (28), formed by using a dry film resist or the like, is provided on the surface of the contact element (25). The insulating film (28) is provided in a process following the forming of the contact element (25) in the manufacturing process for the contact element (25). Thus, an electroformed component where electroformed products can be lined up at a narrow pitch while preserving insulation between the electroformed products (contact elements) is provided.
