Abstract
A method for producing a conductive pattern includes the steps of forming a mask layer on a conductive base plate, the mask layer having a pattern defining an exposed area of the conductive base plate; forming a conductive pattern on the exposed area of the conductive base plate by electroforming using a plating liquid which substantially maintains the pattern of the mask layer; and transferring the conductive pattern onto a support layer without removing the mask layer.
